Omron S8VS-03024 Power Supply — 24 VDC, 30 W DIN Rail Supply for Compact Control Panels

Controls engineers and panel builders searching for the Omron S8VS-03024 are typically at the same decision point: a compact panel, a modest 24 VDC load, limited rail space, and a need for a reliable, approved supply from a trusted automation brand. The S8VS-03024 is a 30 W, 24 VDC, 1.3 A Class 2 switch mode power supply housed in a slim 22.5 mm wide plastic case suitable for DIN rail or direct panel mounting, with a wide input range of 85–264 VAC that covers virtually every single-phase mains voltage worldwide.

If you have already confirmed this is the correct part for your application, check current pricing and availability for the Omron S8VS-03024 at LeadTime.ca — ships worldwide.

Who Should Buy the Omron S8VS-03024 — and Who Should Not

This supply is the right fit when all of the following are true for your application:

  • Your total 24 VDC load, including inrush estimates and a sizing margin, stays comfortably within 30 W and 1.3 A.
  • Your panel supply is single-phase 100–240 VAC (85–264 VAC allowable) or 80–370 VDC input.
  • A slim 22.5 mm book-type plastic housing fits your DIN rail layout or panel mounting arrangement.
  • UL Class 2 output is acceptable or specifically required by your design standard.
  • You do not need a front-panel voltage or current display, monitoring output, or alarm relay on the power supply itself.
  • Operating ambient temperature, including derating at higher temperatures, is within the rated range for this model.

If your load exceeds 1.3 A, if your panel temperature is pushing derating limits, or if you need a monitored supply with front-panel indication, you should be looking at the S8VS-06024 (60 W), the S8VS-12024 (120 W), or an S8VS variant with a built-in display. Those models are covered in the variant comparison table below.

What the Omron S8VS-03024 Actually Does in a Control Panel

The Omron S8VS-03024 is a single-output, switch mode AC/DC power supply that converts single-phase mains voltage — anywhere from 85 to 264 VAC — into regulated 24 VDC at up to approximately 1.3 A. Its role in the system is straightforward: it is the dedicated 24 V rail that keeps PLCs, digital I/O modules, sensors, relays, and small HMIs alive. The 30 W Class 2 output rating makes it well suited to compact OEM machine panels and retrofit enclosures where loads are modest and rail space is at a premium.

The slim 22.5 mm wide plastic housing — what Omron calls the book-type form factor — is a genuine differentiator at this power level. It allows multiple supplies to sit side by side on a 35 mm DIN rail without consuming the panel width that a wider metal-housed supply would demand. The wide input range covering 85–264 VAC and 80–370 VDC means a single part number works across North American 120 V panels and international 230 V installations without any jumper or tap adjustment.

Efficiency is stated at approximately 86% for this model, which in a 30 W supply translates to modest heat dissipation — a practical advantage in sealed or minimally ventilated enclosures. The supply carries a UL Class 2 output designation, which simplifies wiring separation requirements in many North American installations and is a specification that safety-focused designers actively look for in low-power control circuits.

Typical System Architecture for the S8VS-03024

The S8VS-03024 sits between the upstream branch circuit protection and the 24 VDC distribution bus that feeds control-level loads. It is not a high-power bus supply — it is the last conversion stage before individual sensors, I/O cards, and relay coils see their operating voltage.

  • Single-phase mains supply (100–240 VAC) feeds the panel through a main disconnect and branch circuit fuse or breaker.
  • The S8VS-03024 receives AC input at its screw terminals (L, N, and protective earth) and produces regulated 24 VDC at the output terminals.
  • Output connects to a 24 VDC distribution terminal block or bus bar that feeds individual loads.
  • Typical downstream devices include an Omron PLC and I/O modules, photoelectric and proximity sensors, relay coils, and panel indicators.
  • For Class 2 circuits, downstream wiring must remain segregated from higher-voltage circuits in accordance with applicable codes.

Industries and Applications Where the Omron S8VS-03024 Is Specified

The S8VS-03024 appears most frequently in compact OEM machine panels and general industrial automation enclosures where the 24 VDC load inventory is small. In machine building applications — packaging, small assembly stations, and material handling conveyors — the supply powers a modest sensor network, a PLC, and a handful of relay coils without requiring the headroom of a 60 W or 120 W unit.

Panel builders working on HVAC and building automation control panels specify this model when space on the DIN rail is tight and the load profile fits within 1.3 A. The 22.5 mm width allows it to slot into enclosures that cannot accommodate wider metal-case supplies, and the wide input range eliminates the need to stock region-specific variants.

Maintenance engineers replacing failed power supplies in existing panels value the S8VS-03024 as a direct form-factor replacement for older DIN rail supplies in the same power class, particularly where the Omron ecosystem is already standardized across the facility. The Class 2 output rating also makes it a natural fit for dedicated low-power safety interlock circuits where circuit separation is required by the design.

Application Typical Deployment
Small OEM machine panel Powering Omron PLC, a few I/O modules, and panel indicators from a single 30 W Class 2 rail
Sensor network on compact conveyor Supplying 24 VDC to photoelectric and proximity sensors within the 1.3 A limit
Relay and contactor coil panel Driving interposing relays and small contactor coils in a retrofit or upgrade enclosure
HVAC and building automation cabinet Providing regulated 24 VDC to control-level devices in a space-constrained field panel
Class 2 low-power safety circuit Dedicated supply for safety interlocks requiring UL Class 2 separation from higher-voltage circuits

Expert Verdict: Is the Omron S8VS-03024 the Right Supply for Your Panel?

The Omron S8VS-03024 earns its place on the approved parts list for controls engineers and panel builders who need a compact, 24 VDC Class 2 supply for small, well-defined loads. The 22.5 mm slim plastic housing is genuinely useful in tight DIN rail layouts, and the 85–264 VAC wide input range means this single catalog number covers virtually any single-phase mains environment your machine or panel will encounter worldwide. With approximately 86% efficiency at 30 W, heat dissipation in enclosed panels is manageable. For OEM machine builders standardized on Omron controls, this supply integrates naturally without introducing an unfamiliar component into the panel BOM. The UL Class 2 output designation simplifies code compliance on many North American projects, particularly where low-power control circuits must be segregated.

The honest constraint is the 30 W, approximately 1.3 A rating. It leaves limited headroom for panels that will grow over time, for loads with significant inductive inrush, or for situations where ambient temperature derating reduces available output current. If your load calculation is anywhere near the 1.3 A ceiling before margin, the S8VS-06024 at approximately 60 W is the correct choice — not the S8VS-03024 with fingers crossed. Similarly, if your panel design calls for a front-panel supply status indicator, a remote monitoring output, or an audible alarm on power loss, the basic plastic case model without a display will not meet that requirement regardless of power level. Choose the S8VS variant that includes a front-panel monitor for those applications.

From a procurement standpoint, the S8VS-03024 is a mainstream catalog item from a major automation brand, which generally means predictable availability through specialist industrial distributors. For project-level orders, confirming stock and lead time before finalizing a BOM is always the right move — availability can shift with demand and regional inventory cycles. Buying through a specialist distributor gives you access to selection support, load calculation validation, and cross-reference assistance if the exact model is on a longer lead.

What Engineers Need to Know Before Ordering the Omron S8VS-03024

Community-level feedback specifically tagged to the S8VS-03024 catalog number is sparse — engineers discussing power supplies on forums like PLCTalk, PLCS.net, r/PLC, and MrPLC tend to reference the S8VS family or brand-level impressions rather than this individual SKU. What does emerge from the broader S8VS discussion is consistent: the family is described as dependable and compact, a supply you install and largely forget about, provided it is sized correctly from the start. The compact footprint earns consistent recognition from engineers working in tight panels, and the wide input range is noted as a practical convenience for OEM builders shipping machines internationally.

The recurring theme in community discussions — and the source of most ordering regrets — is not product quality but sizing and variant selection. Engineers describe scenarios where a panel load grew after initial commissioning, an S8VS supply that was right on the edge of its rating began exhibiting nuisance shutdowns under inrush conditions, or a supply was ordered and installed before someone realized the panel design actually called for a model with a front-panel status indicator. These are not failures of the product — they are failures of the part selection process, and they are entirely preventable.

The other documented ordering mistake is misreading the S8VS part number structure. The -03024 suffix encodes both the power rating (030 = 30 W) and the output voltage (24 = 24 VDC). Engineers in a hurry have ordered the -03024 when their load required the -06024, or have received a model with a monitoring display when they expected the basic version, or vice versa. When community data is limited and the margin for a wrong-part order is real, the right move is to work through a specialist distributor who can verify the part number against your load calculation and confirm the correct S8VS variant before the order ships.

Wiring and Installation Overview for the Omron S8VS-03024

  • Mount the S8VS-03024 on a 35 mm DIN rail or secure directly to the panel using the panel-mount option, leaving adequate clearance above and below the unit for convective airflow and heat dissipation.
  • Connect single-phase AC input (L and N) and protective earth to the designated input screw terminals using appropriately rated conductors; verify tightening torque against the manufacturer manual.
  • Connect 24 VDC positive and negative output conductors to the output terminals, observing polarity and using conductor sizes rated for the full 1.3 A output current.
  • Install appropriate upstream branch circuit protection — a fuse or circuit breaker rated per the datasheet and applicable local codes — before energizing the supply.
  • For Class 2 output circuits, maintain physical or electrical separation from higher-voltage wiring in accordance with applicable installation codes and the project design standard.

Wrong-Part Prevention Checklist Before Ordering the Omron S8VS-03024

Before placing your order, work through each item on this checklist. These checks are drawn directly from the most common ordering mistakes engineers make with the S8VS family.

  1. Confirm required output voltage is 24 VDC and that all connected loads are 24 V devices.
  2. Calculate total load current and inrush; ensure 30 W / 1.3 A is sufficient with margin.
  3. Verify supply input (single-phase 100–240 VAC) matches the plant voltage and frequency.
  4. Check that UL Class 2 output is acceptable or specifically required by the design.
  5. Confirm DIN rail or panel mounting is acceptable and 22.5 mm width fits the layout.
  6. Check operating temperature and derating curves against panel environment.
  7. Confirm terminal style (screw terminals) and wiring gauge are compatible with field wiring.
  8. Verify you do not actually need a model with front-panel display or monitoring.

If any item on this list raises a question, contact the LeadTime.ca team before ordering — confirming the right variant takes minutes and avoids a costly return or project delay.

Frequently Asked Questions

How much current margin should I leave when sizing loads against the S8VS-03024's 1.3 A rating?

A commonly applied rule in industrial panel design is to leave 20–30% headroom above your calculated maximum continuous load current. At 1.3 A rated output, that means your steady-state load should ideally sit at or below approximately 1.0 A. Beyond continuous current, account for inrush from inductive loads such as relay and contactor coils, which can briefly exceed their steady-state draw. If your load plus margin pushes past the 1.3 A ceiling, move to the S8VS-06024 rather than running the -03024 at its limit.

Can I replace an existing 24 VDC DIN rail supply with the S8VS-03024 without rewiring the enclosure?

In most cases, yes — provided the existing supply uses the same 24 VDC output, has screw terminals compatible with your conductor sizes, and the replacement can physically occupy the same DIN rail position within the 22.5 mm wide footprint. Verify that the rated current of the replacement meets or exceeds the original and that the Class 2 output designation is acceptable under your design standard. Always check the datasheet for terminal torque specifications and conductor sizing before reconnecting.

Is the S8VS-03024 suitable for powering a PLC and servo drives on the same 24 V rail?

Servo drives and motion axes typically have their own dedicated 24 VDC logic supply requirements and can introduce significant inrush when multiple axes enable simultaneously. The S8VS-03024 at 30 W and approximately 1.3 A is generally sized for control-level loads — PLCs, I/O, and sensors — rather than combined control and servo logic rails. For panels that include servo or variable frequency drive control circuits alongside PLC I/O, a higher-power supply or a dedicated supply per load group is the standard approach.

What is the practical difference between the S8VS-03024 and an S8VS model with a front-panel display?

The S8VS-03024 is a basic output-only supply — it provides regulated 24 VDC without any local indication of output voltage or current, no alarm relay, and no monitoring output signal. S8VS variants with a display add a front-panel meter showing output voltage and current, and some include a power-good relay output or alarm contact that can signal a PLC or indicator light when supply voltage drops out of range. If your panel design requires a visual indication of supply health or a monitoring signal to the control system, select the monitored variant explicitly — the -03024 will not provide it.

Does the S8VS-03024 require derating at elevated panel temperatures?

Yes. Like all switch mode power supplies, the S8VS-03024 has a derating curve that reduces available output current as ambient temperature rises above a specified threshold. Operating the supply at or near its 1.3 A rated current in a hot panel without adequate airflow can result in reduced output voltage or thermal shutdown. Always review the derating curves in the current Omron datasheet for this model against your worst-case panel ambient temperature before finalizing the design. If the panel runs warm, either improve ventilation, derate your load budget, or select a higher-rated supply to maintain margin.
