Schneider Electric XVBC2B3 green 70mm LED indicator bank module for Harmony XVB industrial tower light stack

Schneider Electric XVBC2B3 — Indicator Bank, Harmony XVB, Illuminated Unit, Plastic, Green, 70mm, Steady, Integral LED, 24V AC/DC: Specifications, Discontinued Status, and Replacement Guidance

Maintenance technicians and controls engineers searching for the Schneider Electric XVBC2B3 today are almost always dealing with one of two situations: a failed indicator on an existing Harmony XVB stack that needs an immediate replacement, or a legacy system evaluation that requires confirmation of the original specs before ordering. This is a 24V AC/DC, 70mm green LED indicator bank module within the modular Harmony XVB Universal family — a single illuminated unit that stacks with other XVBC modules to build multi-color machine status beacons up to five units high. The critical piece of information every buyer must have upfront: the XVBC2B3 was discontinued on June 30, 2025, placing it approximately nine months past end-of-life as of the date of this review. Stock availability is finite, lead times are uncertain, and ordering decisions should be made with full awareness of what that discontinuation means for your project timeline.

If you have already confirmed this is the right part and need to check current stock status, view the XVBC2B3 product page at LeadTime.ca — we source hard-to-find and discontinued parts and ship worldwide.

Who Should Buy the XVBC2B3 — and Who Should Look at Current-Production Alternatives

The XVBC2B3 is the right call for buyers who are maintaining or repairing an existing Harmony XVB installation and need a direct drop-in replacement. If all of the following are true for your application, this unit fits:

  • Your control circuit supplies 24V AC or 24V DC (the module accepts both without configuration change)
  • Your enclosure or panel has an existing 70mm mounting cutout — not 60mm, not 80mm
  • Your signal scheme requires green indication (steady, continuous-on operation only — no flash function is built in)
  • Your environment demands IP65 or IP66 ingress protection with polycarbonate construction suitable for washdown or chemical exposure
  • You are replacing a failed module in an existing Harmony XVB stack and need dimensional and electrical continuity with installed hardware

If you are specifying for a new machine design, launching a greenfield installation, or building a system that will need parts supply beyond a one-to-two year window, the XVBC2B3 is not the right choice. The discontinuation date has passed, remaining stock is finite, and Schneider Electric's current-production successor models within the updated Harmony XVB line offer better long-term supply security. The same applies if you need flash or strobe capability — the XVBC2B3 is steady-state only, and that cannot be changed within this module.

What the XVBC2B3 Does in a Real Production System

The Schneider Electric XVBC2B3 is a single illuminated indicator module — one lens unit in what is typically a multi-color tower light assembly on a machine or control enclosure. Its job is simple and critical: it tells an operator, a supervisor, or a maintenance technician what the machine is doing right now without requiring them to look at an HMI screen or open a panel. Green typically signals normal operation or a run state, and the XVBC2B3 delivers that signal through a protected integral LED that is powered directly from the 24V control circuit already present in the panel.

What distinguishes the Harmony XVB architecture from a traditional pre-assembled beacon tower is modularity. The XVBC2B3 is one stackable unit within a system that can include up to five independently controlled illuminated modules — green, red, amber, blue, white, or orange — on a single base unit XVBC21. Each module receives its own switched supply from the PLC or control logic, so they operate independently and simultaneously. The polycarbonate lens and body are rated to withstand industrial washdown, chemical exposure, and operating temperatures from -25°C to +50°C, making the family suitable for food and beverage, pharmaceutical, and automotive environments where protection and reliability are non-negotiable.

Two verified characteristics of this product that matter at purchase time: the XVBC2B3 meets more than ten major industrial standards including UL 508, CSA C22.2 No. 14, IEC 60529, and GOST approval, enabling deployment across North American and international installations without re-certification. And the modular stackable design — up to five independent units per base — eliminates the need for separate tower light fixtures or multiple panel cutouts, which is exactly why retrofit teams working in constrained enclosures have relied on the Harmony XVB family for years.

Typical System Architecture for Harmony XVB Indicator Stacks

The XVBC2B3 sits at the output end of the status signaling chain, receiving a switched 24V signal from the control system and converting it to visible green light. Understanding where it fits helps avoid accessory ordering errors.

  • PLC or control relay output supplies switched 24V DC (or AC) to each indicator channel
  • Base unit XVBC21 provides the terminal block where each supply wire connects and physically supports the indicator stack
  • Fixing base XVBZ0 mounts between the base unit and the panel cutout, providing IP65 ingress protection for washdown environments
  • XVBC2B3 (green) and any additional color modules (red XVBCR2B3, amber XVBCO2B3, etc.) stack on top of the base unit — up to five modules total, each independently wired
  • Optional XVBF flash module can be added to the stack if any channel requires strobe or flash output; the XVBC2B3 itself is steady-state only

Where the XVBC2B3 Gets Deployed: Industries and Use Cases

Automotive assembly lines have been one of the most consistent deployment environments for the Harmony XVB family. Tower light stacks using the XVBC2B3 as the green run-state indicator appear on stamping presses, welding cells, conveyor transfer stations, and end-of-line test equipment — anywhere an operator needs immediate visual confirmation that a cycle is running normally without stopping to check a control panel.

Food and beverage processing facilities rely on the IP65/IP66 rated polycarbonate construction for washdown compliance. The XVBC2B3 is regularly found on filling lines, packaging conveyors, and batch mixing equipment where daily sanitizing cycles would destroy indicators with lesser ingress ratings. The same washdown capability makes it a standard choice for pharmaceutical manufacturing equipment where cleaning protocols are strict.

Packaging machinery — cartoners, case erectors, shrink wrappers, palletizers — commonly use Harmony XVB stacks for machine state indication. Maintenance technicians servicing this equipment in the field carry XVBC2B3 units as stock replacement parts because a failed indicator can obscure machine status and slow troubleshooting. Material handling applications including conveyor sorters and ASRS systems use the same logic: continuous visual status feedback is part of the operational workflow, and a failed green indicator needs fast replacement.

Application Typical Deployment
Automotive assembly Green run-state indicator in multi-color stack on welding cell or transfer line; 24V DC PLC output
Food and beverage processing IP65-rated stack on filling or packaging line; washdown environment; polycarbonate lens
Pharmaceutical manufacturing Single or multi-unit stack on batch equipment; IP66 rated via base unit for aggressive cleaning
Packaging machinery Retrofit replacement on existing Harmony XVB stacks on cartoners or case erectors
Conveyor and material handling Status indication on sorter output stations; independently switched green/amber/red stack
HVAC and utility equipment Compressor or chiller run-state indicator; control panel mounted; 24V AC supply

XVBC2B3 vs. Other Harmony XVB Variants: Which One Do You Actually Need?

Model Lens Color Operation Mode Voltage Status
XVBC2B3 Green Steady 24V AC/DC Discontinued June 30, 2025
XVBCR2B3 Red Steady 24V AC/DC Verify current availability
XVBCO2B3 Amber/Orange Steady 24V AC/DC Verify current availability
XVBCB2B3 Blue Steady 24V AC/DC Verify current availability
XVBCW2B3 White Steady 24V AC/DC Verify current availability
XVBF (Flash Unit) N/A Flash/Strobe 24V AC/DC Required separately for flash; verify availability

If your signal scheme requires red for fault or amber for warning alongside the green run-state indicator, you need to order those color variants as separate SKUs — XVBCR2B3 for red, XVBCO2B3 for amber. And if any channel in your stack requires flash or strobe output, the XVBF unit must be ordered as a separate stacked module; there is no way to add flash capability to the XVBC2B3 itself. For a complete three-color stack with flash on the red alarm channel, a typical order would be XVBC2B3 (green) + XVBCR2B3 (red) + XVBCO2B3 (amber) + XVBF (flash) + XVBC21 (base unit) + XVBZ0 (fixing base for IP65). Check current availability and confirm which variants are in stock at LeadTime.ca before finalizing your order list — with a discontinued product, partial stock situations are common.

Expert Verdict: Should You Order the XVBC2B3 or Transition Now?

For a maintenance technician or plant engineer replacing a failed module on an existing Harmony XVB stack, the XVBC2B3 remains a completely viable choice — if stock is confirmed available. The 70mm mounting diameter, 24V AC/DC dual-voltage operation, polycarbonate IP65/IP66 construction, and modular stacking compatibility with existing base units XVBC21 make it a direct drop-in that requires no panel rework, no re-engineering, and no requalification of the surrounding system. Equipment service teams managing automotive lines, food processing equipment, or packaging machinery in the 10-to-15-year age range will find this unit preserves the installed architecture exactly. The combination of UL 508 and CSA C22.2 No. 14 compliance also means it satisfies North American safety requirements without additional documentation burden.

Where the XVBC2B3 is the wrong answer is any scenario involving new machine design, greenfield installation, or a project horizon that extends beyond immediate replacement. As of April 2026, this product is nine months past its June 30, 2025 discontinuation date, and remaining distributor inventory is finite with no production replenishment. If your project cannot afford a 6-to-12-week procurement gap — which is a realistic outcome if available stock is exhausted — specifying the XVBC2B3 creates real schedule risk. For those situations, Schneider Electric's current-production successors in the updated Harmony XVB line are the correct path; they offer equivalent or improved electrical performance and ongoing supply security that a discontinued SKU cannot provide.

The single most important step before committing this part number to a project BOM or work order is confirming actual stock availability in writing with your distributor. Do not rely on website inventory counters for discontinued parts — they frequently lag reality. A specialist automation distributor can check regional distribution center inventory, confirm lead time, and identify the current-production successor model if stock is depleted, all before you commit your timeline. Check the XVBC2B3 product page at LeadTime.ca to see current stock status and request a quote — we ship worldwide and can provide genuine lead-time confirmation on discontinued Schneider parts.

What Engineers Are Reporting About the XVBC2B3 and Harmony XVB Family

Across automation forums including Reddit communities focused on PLC and industrial automation, PLCTalk, and general industrial discussion threads, the Harmony XVB family earns consistent respect for retrofit scenarios. The most frequently cited positive experience is the straightforward module-swap replacement on legacy installations — buyers working on existing Harmony XVB stacks report that replacement units seat correctly and operate immediately without surprises. The polycarbonate construction draws particular praise from engineers in food and beverage and pharmaceutical environments, where deployed units have reportedly held up under daily washdown protocols without visible degradation to the lens or body. The modular stackable architecture is also singled out for enabling multi-color indication retrofits into existing panel cutouts without requiring larger mounting holes or additional panel real estate — a practical advantage in space-constrained machine enclosures that retrofit teams on automotive assembly lines specifically reference.

The frustrations that recur across community discussions cluster around two specific pain points. The first is the discontinuation surprise: buyers who were unaware of the June 30, 2025 end-of-life date encountered mid-project unavailability, and because recommended successor models are not always backward-compatible in terms of mounting footprint or terminal style, some were forced into last-minute redesign work. The second recurring complaint — described by multiple forum contributors as a genuine gotcha — is the base unit dependency. Engineers who ordered the XVBC2B3 module alone discovered at delivery that the base unit XVBC21 must be sourced separately; the indicator module cannot be wired without it. There is also a thread of community discussion around LED brightness longevity in high-temperature deployments, with some field reports of reduced output after 18 to 24 months in ambient conditions approaching the +50°C operating limit. This has not been confirmed against official manufacturer testing data, but it is worth noting for engineers specifying units in consistently hot enclosures.

The ordering mistakes that appear most reliably in community posts are color SKU confusion (ordering green XVBC2B3 when the control scheme required red or amber), mounting diameter mismatches from engineers who assumed all Harmony indicators share the same cutout size, and isolated cases of voltage mismatch where a 24V unit was ordered for a 110V control circuit based on an inherited specification document that had not been verified against the actual installed hardware. These are entirely preventable errors — but they happen with enough regularity that they have earned their place in the wrong-part checklist below.

Installation and Wiring Overview

The following is a practical overview of installation requirements. For complete step-by-step wiring procedures and mounting diagrams, consult the official Schneider Electric installation documentation for the Harmony XVB family.

  • A 70mm panel cutout is required; the base unit XVBC21 must be installed first and provides the screw clamp terminals rated for up to 1 × 1.5 mm² solid or stranded copper wire per connection
  • The XVBC2B3 accepts 24V AC or 24V DC without configuration change; verify your supply is within the 21.24–26.4V operating range before energizing
  • IP65 protection requires the fixing base XVBZ0 to be correctly seated with its mounting gasket; without it, the assembly achieves IP66 via the base unit alone, which may be sufficient for many environments
  • Each stacked module connects to its own independent terminal pair on the base unit; up to five modules can be stacked, each individually switched from PLC or relay outputs
  • No internal circuit protection is included — an external circuit breaker or fuse rated for the combined current of all installed modules (each drawing less than 47 mA) must be present upstream before commissioning

Compatible Accessories and System Components

A complete Harmony XVB installation using the XVBC2B3 typically requires some or all of the following components, depending on your configuration. Verify availability for all items when ordering, particularly for discontinued SKUs.

  • XVBC21 (Base Unit) — Required for all installations; provides terminal block for 24V supply connections and physical support for the indicator stack; must be ordered separately
  • XVBZ0 (Fixing Base) — Provides IP65 ingress protection when installed between base unit and panel cutout; recommended for washdown environments
  • XVBF (Flash Unit) — Optional strobe/flash module that stacks with XVBC illuminated units; required if any channel needs flash or strobe output (XVBC2B3 is steady-state only)
  • XVBCR2B3 (Red Unit) — Steady red indicator module for fault or stop-state signaling; same family, same base unit, same voltage
  • XVBCO2B3 (Amber/Orange Unit) — Steady amber indicator for warning state; stacks alongside green and red units
  • XVBCB2B3 (Blue Unit) and XVBCW2B3 (White Unit) — Additional color options for expanded signal schemes; up to five total units per base

Wrong-Part Prevention: Verify These Seven Points Before You Order

The XVBC2B3 is frequently ordered incorrectly. Work through this checklist before submitting a purchase order — each item corresponds to a real mistake documented in the field.

  1. Verify mounting diameter: 70mm mounting ring (not 60mm, not 80mm). Check existing fixture or control panel documentation.
  2. Confirm voltage requirement: 24V AC/DC (not 110V, not 240V). Check control circuit schematic or PLC output specifications.
  3. Lens color: Green specifically (do not confuse with red XVBCR, amber XVBCO, blue XVBCB). Check status signal requirements.
  4. Steady operation only: This is steady state (not flash/strobe). If flash capability required, order XVBF separately or source flash-capable model.
  5. Base unit requirement: Verify if XVBC21 base unit is already installed or must be ordered separately for first installation.
  6. LED vs. incandescent vs. discharge tube: Confirm this is LED version (lower power, longer life). Datasheet shows incandescent and discharge options also available in product line.
  7. Discontinued status: Confirm with distributor if stock is available; plan transition timeline to successor model. Do not assume long-term availability.

If you are unsure about any of these points before ordering, contact the LeadTime.ca team — we can confirm spec compatibility against your existing installation details and verify current stock status on discontinued parts before you commit.

Frequently Asked Questions

Is the XVBC2B3 still available to purchase, or is it truly gone?

The XVBC2B3 was officially discontinued on June 30, 2025. As of April 2026, limited stock may still be available through authorized distributors who purchased inventory prior to end-of-life. Availability is not guaranteed and changes without notice — confirm with your distributor in writing before specifying this part on a work order or project BOM. Do not assume web-listed availability reflects actual current stock.

Does the XVBC2B3 come with the base unit, or do I need to order XVBC21 separately?

The base unit XVBC21 must be ordered separately. The XVBC2B3 is a single illuminated indicator module only — it has no integral terminal connections and cannot be wired without the base unit. This is one of the most commonly reported ordering mistakes in the field. For a first-time installation, your order must include XVBC2B3, XVBC21, and XVBZ0 (if IP65 protection is required).

Can I add a flash or strobe function to the XVBC2B3?

No — the XVBC2B3 operates in steady (continuous-on) mode only. Flash capability cannot be added to this module. If you need a flashing or strobe output on any channel in your indicator stack, you must order the separate XVBF flash unit and stack it with the XVBC units on the base. Verify XVBF availability when ordering given the family's partial discontinuation status.

Does the XVBC2B3 work with both 24V AC and 24V DC, or do I need a different version for DC?

The XVBC2B3 accepts both 24V AC and 24V DC without any configuration change or jumper selection. The operating voltage range is 21.24 to 26.4V. This dual-voltage capability is one of the practical advantages of this family for retrofit work, as it integrates with both legacy AC control circuits and modern DC PLC output cards on the same part number.

What is the difference between IP65 and IP66 on this unit, and which do I need?

IP65 is achieved when the XVBC2B3 is installed with the fixing base XVBZ0, providing protection against directed water jets. IP66 applies when mounted directly on the base unit XVBC21 without the fixing base, providing a higher level of water resistance. For standard washdown environments, IP65 with XVBZ0 is typically sufficient. For severe washdown or high-pressure cleaning, confirm whether IP66 is required and verify the mounting configuration delivers it.

Does the XVBC2B3 require external circuit protection, and what should it be rated for?

Yes — the XVBC2B3 includes no internal circuit breaker. An external overload protection device must be installed upstream in the control circuit. Each unit draws less than 47 mA; calculate the total current for all modules in your stack and size the protection device accordingly, with appropriate safety margin. If this protection device is missing from your existing installation, it must be added before commissioning a replacement unit.
