Does the Omron S8FS-G10024CD Fit Your Project Requirements?

This power supply is the right fit for engineers and panel builders who need a certified, metal-housed 24 V DIN rail supply in the 100 W class. Specify it when all of the following apply:

  • Your total 24 V DC load, including a safety margin and derating allowance, sits within 4.5 A and 100 W continuous output.
  • Your input supply is single-phase AC within the 100–240 VAC wide-range input.
  • Your panel accommodates DIN rail mounting with a covered housing and screw terminal block connections.
  • Ambient operating conditions fall within -20 to 70 °C with adequate ventilation for natural convection cooling.
  • Your project requires UL 508 listing, CSA C22.2, EN 50178, and EN 61204-3 EMC class B compliance.

If your load exceeds 100 W, your output voltage requirement is different from 24 V DC, or your project demands ultra-compact form factor, advanced digital diagnostics, or built-in redundancy, you should evaluate other S8FS-G wattage variants or a different Omron power supply family instead.

What the S8FS-G10024CD Actually Does in a Control Panel

The S8FS-G10024CD occupies a specific and very common role in industrial control systems: it is the primary source of regulated 24 V DC control power for PLCs, remote I/O modules, HMIs, sensors, relays, contactors, and safety devices in a panel or machine enclosure. It takes whatever single-phase AC voltage the facility provides — anywhere in the 100–240 VAC range — and converts it to a stable, isolated 24 V DC rail that the control devices depend on.

What separates it from generic or off-the-shelf supplies is the combination of a covered metal housing, DIN rail mounting, screw terminal connections, and the full set of industrial certifications: UL 508, CSA C22.2, EN 50178, and EN 61204-3 EMC class B. The aluminum and stainless steel case provides greater resistance to rusting compared to sheet steel or plastic enclosures, which matters in environments with humidity, cleaning agents, or mild chemical exposure. The covered design keeps contaminants off the internal components while still relying on natural convection for cooling — no fans, no additional maintenance items.

This is not a PSU you buy for its diagnostic display or network connectivity. It is a PSU you buy because 100 W at 24 V DC covers a broad range of small and mid-size panel loads, it mounts on a standard DIN rail, and it will be accepted by inspectors who check for UL and CSA marks without additional paperwork.

Typical System Architecture for a 24 V DIN Rail Power Supply

The S8FS-G10024CD sits at the power conversion layer of the control panel, between the incoming AC distribution and the 24 V DC load bus. Here is how a typical deployment looks:

  • Single-phase AC feed (100–240 VAC) arrives at a circuit breaker or fused disconnect inside the panel enclosure.
  • The S8FS-G10024CD receives the protected AC input at its screw terminal block and converts it to a regulated 24 V DC output rail.
  • The 24 V DC output feeds a terminal distribution block or fused output module, which branches power to individual loads.
  • Downstream loads on the 24 V rail include PLC CPUs, I/O modules, HMI panels, sensors, relay coils, contactors, and safety relay modules.
  • The protective earth terminal on the power supply connects to the panel ground bus, completing the safety grounding circuit for all downstream 24 V devices.

Industries and Applications Where This PSU Is Specified

The S8FS-G10024CD is a general-purpose industrial power supply, which means its application footprint is broad. In machine tool environments, the 100 W continuous rating and -20 to 70 °C operating temperature make it a natural fit for control cabinets mounted close to CNC or cutting machinery where temperatures and vibration are elevated.

Semiconductor and electronics manufacturing equipment specifies this model where corrosion resistance and stable 24 V control power are required for tool subsystems, and where UL and EN certifications are non-negotiable for facility and insurance compliance. The metal housing addresses the concern about chemical exposure in cleanroom-adjacent environments.

Material handling and packaging machinery are perhaps the most common application class. A compact control cabinet powering a PLC, safety relay, motor starters, and photoelectric sensors will typically draw well within the 4.5 A limit at 24 V, making this an appropriately sized supply without the cost of oversizing to a 150 W or 200 W unit.

OEM panel builders also use the S8FS-G10024CD as a standard component across a range of machine variants. When a single PSU can cover the majority of configurations in a product line, it simplifies BOM management, spare parts stocking, and field service.

Application Typical Deployment
Machine tool control cabinet Primary 24 V supply for PLC, I/O, relays, and operator panel in a floor-standing enclosure
Semiconductor equipment subsystem Control power for tool electronics where corrosion resistance and certifications are required
Packaging and material handling line 24 V rail for sensors, safety devices, and motion control I/O in a compact panel
OEM standard panel build Single PSU model covering multiple machine variants in a standardized 24 V / 100 W class
Process control skid 24 V DC supply for transmitters, solenoid valves, and field device loops in a skid-mounted enclosure
Panel retrofit or upgrade Replacement for aging PSU in existing panel, wide AC input accommodates varying facility voltages

S8FS-G10024CD vs Other S8FS-G Variants: Which One Do You Need?

The S8FS-G family spans a power range from 15 W up to 600 W, with multiple output voltage options including 5 V, 12 V, 24 V, and 48 V. The S8FS-G10024CD is specifically the 100 W, 24 V, covered, DIN rail, screw terminal variant. Understanding the catalog suffix structure prevents ordering the wrong part. The "C" and "D" characters in the suffix indicate the mounting and housing configuration — a different suffix in the same family changes the mechanical format, not just the wattage.

Model Output Power Output Voltage Output Current Mounting / Housing
S8FS-G10024CD 100 W 24 V DC 4.5 A Covered, DIN rail, screw terminal
S8FS-G family (lower wattage) 15–60 W range 24 V DC (and others) Lower than 4.5 A Covered or other mounting styles
S8FS-G family (higher wattage) 150–600 W range 24 V DC (and others) Higher than 4.5 A Various mounting options
S8FS-G family (different voltage) Various 5 V, 12 V, or 48 V Varies by model Covered or other mounting styles

If your total load with margin and derating exceeds the 100 W continuous rating of the S8FS-G10024CD, move to the next wattage tier in the S8FS-G family rather than running this unit at its limit. Check current availability and compare variants at LeadTime.ca.

Expert Verdict: Who Should Buy the S8FS-G10024CD

The S8FS-G10024CD is the right choice for controls engineers, OEM machine designers, and panel builders who need a certified, metal-housed 24 V DC supply at the 100 W class and who value a recognized brand with broad approval coverage over advanced diagnostics or minimum footprint. The -20 to 70 °C operating range and the aluminum and stainless steel housing make it meaningfully better suited to harsher industrial environments than basic commercial-grade DIN rail supplies. The wide 100–240 VAC input means the same part number works across facilities with different supply voltages, which is a genuine advantage for OEMs shipping equipment to multiple regions or for integrators building panels for international customers. The four verified certifications — UL 508, CSA C22.2, EN 50178, and EN 61204-3 class B — cover the approval requirements of most industrial projects in North America and Europe without needing supplementary EMC filters or additional compliance paperwork.

There are real cases where a different part is the better call. If your panel space is extremely tight, the approximately 167 x 97 x 39.2 mm footprint may drive you toward a more compact Omron PSU family. If your application requires built-in redundancy management, active current sharing, or digital diagnostics with bus communication, the S8FS-G series is not designed for those functions and you should look at Omron's more feature-rich power supply families. If your required output power is significantly higher or lower than 100 W, or if your output voltage requirement is 5 V, 12 V, or 48 V rather than 24 V DC, select the appropriate S8FS-G variant rather than trying to adapt this model.

From a procurement standpoint, the S8FS-G10024CD is typically held in stock at major North American automation distributors, but extended lead times are possible during high-demand periods or supply constraints. Ordering through a specialist distributor rather than a broad-line channel gives you the ability to confirm that the exact suffix and catalog number matches your mechanical and approval requirements before the order ships — a check that has saved many panel builds from costly wrong-part delays.

Price, Lead Time, and Availability in Canada and Worldwide

The S8FS-G10024CD occupies the mid-range price tier for branded 24 V / 100 W DIN rail industrial power supplies. It costs more than no-name or entry-level DIN rail supplies, which reflects the metal housing, the full UL/CSA/EN approval set, and Omron's manufacturing and support infrastructure. It is priced below premium redundant or digitally monitored PSU systems that add features most standard panel applications do not need. Pricing is available directly on the product page, and LeadTime.ca's pricing reflects live market conditions — no estimate here will substitute for checking the current figure before you quote a project.

In North America, the S8FS-G10024CD is typically stocked at major automation distributors, and Canadian buyers can generally expect similar stock availability to US inventory through multinational distribution channels. That said, high-demand periods or supply chain constraints can extend lead times to multiple weeks, particularly for larger order quantities. Canadian procurement should also factor in landed cost, applicable tariffs, and shipping when comparing total cost against US-sourced quotes. All of these variables are confirmed at time of order, not at time of specification — which is another reason to verify with a distributor before locking in a project timeline.

What Engineers Need to Know Before Ordering the S8FS-G10024CD

Model-specific community discussion for the S8FS-G10024CD is sparse. A search across Reddit communities including r/PLC, r/automation, and r/industrialautomation, as well as PLCTalk, PLCS.net, MrPLC, and distributor Q&A sections, produced very limited direct user feedback on this exact catalog number. Expanding the search to the S8FS-G family as a whole yielded only general observations about DIN rail power supplies broadly. This is actually consistent with how well-specified industrial components behave: a reliable, properly applied PSU generates no forum threads because there is nothing to report.

When community data is thin, the wrong-part and wrong-application risks become the most important guidance available. The recurring ordering mistakes that do appear in general PSU discussions are directly applicable here. Buyers confuse closely related catalog numbers that differ only in mounting style or housing type — the suffix characters in S8FS-G10024CD carry specific meaning, and substituting a similar-looking part number without verifying the descriptor can result in receiving an open-frame or differently mounted variant that does not fit the panel. Undersized selection is the other consistent error: engineers calculate steady-state load current correctly but omit the derating correction for ambient temperature and enclosure conditions, then find the supply trips or derates under normal operating conditions. A third pattern is approvals oversight — selecting a PSU without confirming the exact certification marks needed for the jurisdiction and installation type, then facing rework when the inspection fails.

When community feedback is not available to validate a specification, consulting a specialist distributor before ordering is the most direct risk-reduction step. LeadTime.ca can confirm that the S8FS-G10024CD catalog number and suffix match your mechanical, electrical, and approval requirements, identify equivalent options if stock is constrained, and help you avoid the lead-time delays that come from receiving the wrong variant and having to reorder.

Wiring and Installation Overview

  • De-energize all related circuits and verify isolation before mounting or wiring; mount the S8FS-G10024CD securely on a DIN rail with clearance above and below for natural convection cooling — the covered housing relies entirely on airflow, not fans.
  • Connect the protective earth (PE) terminal first, then wire the AC input terminals using conductors appropriately rated for the installation and protected by external upstream overcurrent devices (fuses or circuit breakers) as required by local electrical codes and the Omron datasheet.
  • Connect the 24 V DC output terminals to the load distribution point — terminal blocks, fused output modules, or directly to loads — using the correct wire gauge for 4.5 A maximum current and observing polarity markings.
  • Verify all screw terminal connections are tightened to the specified torque, apply ferrules or end sleeves where required by your wiring standards, and ensure strain relief is in place to prevent mechanical stress on the terminals.
  • Re-energize the AC input, measure the 24 V DC output voltage under no-load and then under full load to confirm correct regulation, and inspect for any LED status indicators per the Omron datasheet before handing off to commissioning.

Wrong-Part Prevention Checklist

Before placing an order for the S8FS-G10024CD, work through every item on this checklist. A single missed check is the most common cause of the wrong part arriving on site.

  1. Confirm required output is 24 V DC and that 4.5 A (100 W) is sufficient for all loads plus safety margin and derating.
  2. Verify input supply is compatible with the S8FS-G10024CD's rated AC input range (100–240 VAC single-phase).
  3. Check that DIN rail mounting and covered housing are acceptable for the panel design (vs open-frame or chassis-mount).
  4. Confirm ambient temperature, enclosure ventilation, and mounting orientation support operation up to the required temperature without excessive derating.
  5. Verify that the screw terminal block connection style matches wiring standards and installer preference.
  6. Confirm compliance requirements (UL 508 listing, CSA, EN standards, EMC class B) align with the project's regulatory needs.

If any item on this list cannot be confirmed before ordering, contact the LeadTime.ca team to verify before placing the order — ships worldwide.

Frequently Asked Questions

What is the actual difference between the S8FS-G10024CD and other S8FS-G10024 variants in the same family?

The suffix characters in the catalog number indicate the mechanical and housing configuration of the unit. The S8FS-G10024CD specifies a covered housing with DIN rail mounting and a screw terminal block. Other S8FS-G variants at the same wattage and voltage may use a different mounting style, an open-frame housing, or a different terminal configuration. These are not interchangeable mechanically — always verify the full catalog number and the written descriptor (covered, DIN rail, screw terminal) matches your panel requirements before ordering.

How do I correctly size the S8FS-G10024CD for my PLC and I/O load without triggering overload or derating?

Sum the steady-state current draw of all 24 V DC loads — PLC CPU, I/O modules, HMI, sensors, relay coils, and any other devices on the rail. Apply a safety margin (typically 20–30% headroom above calculated load) and then apply the derating correction for your worst-case ambient temperature and enclosure conditions per the Omron datasheet derating curve. If the resulting required current with margin and derating stays within 4.5 A, the S8FS-G10024CD is correctly sized. If it exceeds 4.5 A or 100 W, move to the next wattage tier in the S8FS-G family.

Can the S8FS-G10024CD be used in a high-temperature enclosure or at high altitude without modification?

The S8FS-G10024CD is rated for operation from -20 to 70 °C and up to approximately 3000 m altitude. However, both elevated temperature and altitude require derating — the unit cannot deliver its full 100 W / 4.5 A output at the extremes of these ranges. Consult the Omron datasheet derating curves for your specific ambient temperature and altitude before confirming the unit will cover your load budget. Adequate ventilation clearance above and below the unit is essential for the natural convection cooling to function correctly.

What external protection devices are required when installing the S8FS-G10024CD?

The S8FS-G10024CD requires external upstream overcurrent protection on the AC input — a correctly rated circuit breaker or fuse selected per local electrical codes and the Omron installation documentation. The PSU's internal protections cover the output side for overload, short-circuit, and overvoltage conditions typical of industrial SMPS design, but the AC input protection and the protective earth connection are the installer's responsibility. Verify specific protection requirements in the Omron datasheet and applicable wiring codes for your jurisdiction.

If the S8FS-G10024CD is out of stock, what are the closest alternatives to evaluate?

When the S8FS-G10024CD is unavailable, the first options to evaluate are other S8FS-G family models at the same 100 W / 24 V rating with a compatible mounting configuration, as these are the most direct catalog substitutes within the Omron family. Other Omron PSU families at 24 V / 100 W may offer different form factors or features but require mechanical and approval verification before substitution. Any non-Omron 24 V / 100 W DIN rail supply used as a substitute must be independently verified for wiring compatibility, approval equivalency for your jurisdiction, and physical fit — it is not a drop-in replacement without that confirmation. Contact LeadTime.ca to check current stock and qualified alternatives.
