Omron S8VS-09024 Power Supply, 90W, 100–240 VAC Input, 24 VDC 3.75 A Output, DIN Rail Mounting, Basic Model — Specs, Pricing and Alternatives Guide

Controls engineers and panel designers searching for the Omron S8VS-09024 are typically at the same decision point: they have confirmed they need a 24 VDC rail in the 3–4 A range for a small to mid-sized control panel, and they are validating whether this specific 90 W basic model is the right call before it goes on the BOM. The Omron S8VS-09024 is a single-output AC/DC DIN rail switching power supply rated at 24 VDC, 3.75 A, and 90 W, accepting a wide allowable input range of approximately 85–264 VAC — making it compatible with mains voltages across virtually every industrial installation worldwide. What follows is a peer-level review of where this supply fits, where it does not, and what to confirm before ordering.

Who Should Buy the Omron S8VS-09024 — and Who Shouldn't

The Omron S8VS-09024 is the right choice for engineers and buyers who need a dependable, brand-name 24 VDC supply in the 90 W class for a standard industrial control panel. This is the right part if:

  • Your plant mains is single-phase within the approximately 85–264 VAC allowable range (or 80–370 VDC), and you need a wide-input supply that works globally.
  • Your total continuous 24 VDC load — including PLCs, I/O modules, sensors, relays, and HMIs — sums to no more than roughly 70–80% of the 3.75 A rating under steady-state conditions, with headroom for peaks.
  • You need a basic model without a front-panel digital display or alarm/status output contacts — the plain S8VS-09024 has neither.
  • Your enclosure can accommodate a 50 mm wide, 120.4 mm high, 121.3 mm deep DIN-rail mounted unit with adequate clearance for cooling airflow.
  • You are building a repeat OEM panel design, replacing a failed S8VS-09024 in existing equipment, or specifying for a brownfield upgrade where the S8VS family is already in use.

If your application requires a built-in status display or alarm contact outputs, the correct parts are the S8VS-09024A or S8VS-09024B monitor variants. If panel space is critically tight and maximum footprint efficiency matters, evaluate the Omron S8VK series before committing to the S8VS.

What the Omron S8VS-09024 Actually Does in a Control Panel

The Omron S8VS-09024 belongs to Omron's established S8VS family of DIN-rail mounted AC/DC switching power supplies — a range that has been a staple of industrial control panels across factory automation, packaging machinery, and OEM equipment for many years. Its job is straightforward: take single-phase mains voltage from the plant distribution system and deliver a stable, regulated 24 VDC rail at up to 3.75 A to power the low-voltage control circuit inside the panel.

What defines this specific catalog number is the combination of its 90 W output class, its 24 VDC nominal output, and its designation as the basic S8VS variant — meaning no front-panel digital meter and no alarm or status output contacts. It is a clean, unfussy supply that converts efficiently at approximately 84% under rated conditions, which translates to less waste heat inside the enclosure compared with older linear supplies. The allowable AC input range of approximately 85–264 VAC, and an allowable DC input of approximately 80–370 VDC, means it operates correctly on North American 120 V mains, European 230 V systems, and most industrial distribution voltages in between without any manual voltage selection.

In practical terms, the S8VS-09024 powers the 24 V bus that keeps the PLC scanning, feeds the I/O modules receiving sensor signals, drives relay coils and contactor pilot circuits, powers the HMI display, and supplies field instruments. At 3.75 A it sits in a useful mid-range: enough for a small to mid-sized panel without the cost and bulk of a 120 W or 180 W unit, and with genuine headroom over a 60 W supply when inrush currents from solenoids or contactors are part of the load profile.

Where the S8VS-09024 Sits in a Typical System Architecture

The S8VS-09024 is the upstream power conversion node in the 24 VDC control circuit — it takes mains AC from the panel's incoming power section and feeds every 24 V consumer downstream. A typical component chain looks like this:

  • Plant mains distribution (120 VAC or 230 VAC single-phase) feeds through the panel's main disconnect and upstream overcurrent protection (fuse or breaker — required externally; not internal to the S8VS-09024).
  • AC input terminals (L, N, PE) of the S8VS-09024 receive the protected mains supply.
  • The 24 VDC output terminals (+, –) feed a 24 V distribution block or terminal strip in the panel.
  • From the distribution block, individual fused branches supply the PLC CPU and I/O rack, HMI, safety relays, and sensor/field device circuits.
  • Inductive loads such as solenoid valves and contactor coils should be fused separately at the 24 V distribution point to isolate fault currents from logic supply loads.

Typical Applications and Deployment Scenarios

The 90 W, 3.75 A rating of the Omron S8VS-09024 is well matched to the most common size of industrial control panel — one that supports a small PLC with a modest I/O rack, a handful of field devices, relay coils, and an operator interface. This is the configuration found in standalone OEM machinery for packaging, assembly, material handling, and machine tool applications.

In factory automation, the S8VS-09024 is a natural fit for Omron PLC platforms and their associated digital and analog I/O modules, where staying within the Omron ecosystem provides straightforward compatibility. It is equally at home powering third-party PLCs, field instruments, and mixed-brand I/O — 24 VDC is an industry-standard control voltage and the S8VS-09024 is not restricted to Omron loads.

Maintenance and MRO teams frequently specify this model as a direct like-for-like replacement when an existing S8VS-09024 fails in installed equipment. Because the form factor, DIN-rail footprint, and terminal arrangement are consistent within the S8VS family, replacement is typically a panel-level swap without rewiring the distribution block.

Panel builders creating standard design templates for OEM product lines often base their 24 V power section on a fixed supply that covers the majority of machine configurations. The S8VS-09024 fills that role where total 24 V load for the baseline machine option runs comfortably below 3 A, with the 3.75 A rating providing headroom for optional extras without forcing an upgrade to the next model up.

Application Typical Deployment
OEM packaging machinery Powers PLC, digital I/O, sensors, and pilot relays in a compact machine panel
Material handling conveyor control Supplies 24 V bus for motor starter pilot circuits, proximity sensors, and an HMI
Machine tool control panel Dedicated 24 VDC rail for CNC I/O, safety relays, and indicator circuits
MRO direct replacement Like-for-like swap of failed S8VS-09024 in existing installed equipment
Process skid control cabinet 24 V supply for field transmitters, solenoid valves, and PLC I/O on a small process skid
Retrofit HMI or expansion I/O Dedicated 24 VDC rail added to an existing machine for a new touchscreen or I/O block

Within the S8VS family, the key selection decisions run along three axes: output power class, output voltage, and whether you need monitoring features. The table below maps the most common variant comparisons that come up at the point of purchase.

Model Output Power Output Voltage / Current Monitor / Display Best Use Case
S8VS-06024 60 W 24 VDC / 2.5 A None (basic) Smaller panels with lighter 24 V loads; not suitable where inrush peaks approach 3 A
S8VS-09024 90 W 24 VDC / 3.75 A None (basic) Standard small to mid-sized control panels; no display or alarm contacts required
S8VS-09024A 90 W 24 VDC / 3.75 A Digital display + alarm output Same load profile as S8VS-09024 but with front-panel voltage/current readout and alarm relay
S8VS-09024B 90 W 24 VDC / 3.75 A Digital display + status output Applications needing front-panel diagnostics and a status contact for PLC monitoring
S8VS-12024 120 W 24 VDC / 5 A None (basic) Panels with heavier inductive loads or more I/O where 3.75 A is borderline

If your load calculation puts you consistently above 3 A continuous, or if you anticipate significant panel expansion, the S8VS-12024 at 5 A is the logical next step — check current availability and compare models at LeadTime.ca.

Expert Verdict: Is the Omron S8VS-09024 the Right Supply for Your Project?

For controls engineers specifying a 24 VDC rail in the 3–4 A class for a small to mid-sized control panel, the Omron S8VS-09024 is a very sound default. It delivers stable regulated 24 VDC output at 3.75 A from a wide input range — approximately 85–264 VAC — which means it works correctly on virtually any single-phase mains supply worldwide without jumper changes or transformer taps. At approximately 84% efficiency under rated conditions, it generates less heat than older linear supplies of equivalent rating, which matters in compact enclosures. The approximately 50 mm DIN-rail footprint is wider than the newest slim-line generation, but for the majority of standard panel layouts it is entirely workable. This is the supply to specify with confidence for brownfield upgrades, repeat OEM designs where S8VS is already the standard, and direct MRO replacements on installed equipment.

Where the S8VS-09024 has real limits is worth stating directly. At 50 mm wide it will be noticeably bulkier than units from the Omron S8VK series in panels where DIN rail space is a premium. It also has no built-in diagnostic capability — no voltage/current display, no alarm contact output, no status relay — so if the application needs the supply to flag a problem to the PLC or to an operator panel lamp, the S8VS-09024A or S8VS-09024B are the correct models. For new designs where energy efficiency, footprint minimization, or integrated diagnostics are primary criteria, evaluating the S8VK family before locking in the S8VS is a legitimate step. And if load calculations push consistently past 3 A continuous, the S8VS-12024 at 5 A provides the right headroom without oversizing dramatically.

From a procurement perspective, the S8VS-09024 is an established catalog item through Omron-authorized distribution channels worldwide, and it is commonly held in stock or available to order with lead times that reflect its mature product status. That said, older S8VS family models can occasionally appear on extended lead time or face regional stock fluctuations — particularly in MRO scenarios where a single failed unit is urgently needed. Buying through a specialist industrial automation distributor rather than a general-purpose marketplace is the practical safeguard here: a knowledgeable distributor can confirm whether the S8VS-09024 is the right-generation part for your specific panel, verify current lead times before you commit to a build schedule, and proactively suggest a form-fit-function alternative in the S8VK family if availability becomes a project risk.

What Engineers Need to Know Before Ordering the Omron S8VS-09024

Model-specific forum threads for the S8VS-09024 are limited in volume — most community discussion happens at the S8VS family level, and the engineers who have been using these supplies for years tend not to post extensively about hardware that simply works. What that silence actually communicates is meaningful: across the automation forums where controls engineers do post about power supply problems — Reddit r/PLC, PLCTalk, PLCS.net, MrPLC — the Omron S8VS family consistently draws the label of workhorse. Users describe years of continuous service in panels that see industrial temperature cycling and vibration, with stable 24 V output and none of the voltage sag under varying load that occasionally gets reported with lower-cost DIN supplies. The recurring praise for familiar DIN-rail mounting and standard screw terminals reflects how much installers and maintenance technicians value hardware that behaves predictably during a field replacement under time pressure.

Where community discussion does get specific, it tends to cluster around selection and sourcing mistakes rather than field failures. The most common theme is the confusion between the basic S8VS-09024 and the monitor variants — engineers who expected a front-panel voltage and current display have discovered after delivery that the base catalog number includes neither. A related error involves the very similar part numbering between voltage variants: the S8VS-09012 (12 V output) shares its power class with the S8VS-09024 (24 V output), and the two digits that differ are easy to overlook in a BOM or purchase order. The third recurring mistake is undersizing: selecting a 60 W S8VS to save cost, then finding the supply nuisance-trips or runs near its thermal limit when inrush from contactors or solenoid valves hits at startup. The 90 W rating of the S8VS-09024 was chosen by many engineers precisely to avoid that margin problem, and it is a legitimate reason to stay with this model rather than the smaller 60 W sibling.

The sourcing reality that comes up in community threads and distributor Q&A sections is also worth flagging: some S8VS models in this family have started to see longer lead times as the product line ages relative to the newer S8VK generation, and in certain regions stocking levels vary by timing and channel. For MRO replacements where an unplanned failure puts a machine down, this is not an academic point. Engineers who have navigated this situation consistently recommend two practices: verify availability with an authorized distributor before assuming same-week delivery, and evaluate whether the S8VK family offers a compatible replacement footprint that is better stocked in your region for future builds. When community-sourced guidance is sparse and manufacturer documentation does not address your specific configuration question, the right move is to consult with a specialist distributor who works with this hardware daily.

Wiring and Installation Overview

The following bullets summarize the key requirements for installing the Omron S8VS-09024. For complete wiring diagrams, torque specifications, conductor sizing tables, and commissioning procedures, consult the official Omron S8VS instruction sheet and datasheet for this catalog number.

  • Mount the S8VS-09024 on a 35 mm DIN rail in the book-type (upright) orientation specified by Omron, with adequate clearance above, below, and to the sides for cooling airflow — thermal derating begins if ventilation is restricted.
  • Connect AC input (L, N) and protective earth (PE) using wire sizes and types per the Omron datasheet; external upstream overcurrent protection is required and is not provided internally by the S8VS-09024.
  • Connect the 24 VDC output (+, –) to a distribution terminal block, observing polarity; use separate fused branch circuits from the 24 V distribution point for logic loads and inductive field loads to isolate fault currents.
  • Torque all screw terminals to the values specified in the Omron installation documentation; check that no bare copper is exposed at terminals and that conductors are fully seated.
  • After initial energization at light load, verify 24 VDC output at the distribution block before connecting the full load; confirm no LED fault indication is present and that output voltage is within the expected regulation band.

What to Confirm Before You Place the Order — Wrong-Part Prevention Checklist

The single most common source of ordering errors on DIN rail power supplies is assuming the part number is close enough. For the Omron S8VS-09024, run through this checklist verbatim before submitting the order:

  1. Confirm output voltage is 24 VDC (not 12 V, 5 V, or other S8VS variants).
  2. Confirm output power is 90 W / 3.75 A and that total continuous load (plus headroom) stays below this value.
  3. Check you really want the basic S8VS-09024 (no front display/alarm) and not S8VS-09024A or S8VS-09024B.
  4. Verify input supply is single-phase within the allowable 85–264 VAC (or 80–370 VDC) range and compatible with your plant power.
  5. Check physical dimensions (approx. 50 mm W x 120.4 mm H x 121.3 mm D) fit your DIN rail and enclosure.
  6. Confirm ambient temperature, ventilation, and mounting orientation meet Omron's derating and installation guidelines.
  7. Ensure required approvals (UL, CE, etc.) and any Class 2 requirements are met by this exact catalog number.
  8. For replacements, match full model string from the old unit's nameplate (including any /ED2 or regional suffix) before ordering.

Frequently Asked Questions

Can I parallel two Omron S8VS-09024 units to get more than 3.75 A on a shared 24 V bus?

The S8VS-09024 is a basic model without built-in active current-sharing circuitry, and Omron's documentation does not specify parallel operation as a supported configuration for standard models in this family. If your load requires more than 3.75 A continuous, the correct approach is to select a higher-rated supply within the S8VS or S8VK family, or to use separate supplies feeding separate distribution branches. Consult the Omron datasheet and, if needed, contact LeadTime.ca to identify the correctly rated model for your load.

What is the difference between the S8VS-09024 and the S8VS-09024A or S8VS-09024B?

All three models share the same 90 W, 24 VDC, 3.75 A electrical ratings and the same physical form factor. The distinction is in the monitoring features: the S8VS-09024 is the basic model with no front-panel display and no alarm or status contact outputs. The S8VS-09024A adds a front-panel digital meter with alarm output contacts, and the S8VS-09024B adds a display with a status output. If the machine drawing or existing unit nameplate shows an A or B suffix, that suffix is functionally significant — ordering the base S8VS-09024 in its place will leave the panel without the diagnostic or interlock wiring it was designed for.

How much current headroom should I leave between my calculated 24 V load and the 3.75 A rating?

A practical rule used by controls engineers is to keep continuous steady-state load to no more than 70–80% of the rated output current, which translates to roughly 2.6–3.0 A for the S8VS-09024 under normal operating conditions. This margin accommodates inrush from solenoids and contactors switching simultaneously, allows for future I/O or sensor additions, and keeps the supply operating below its thermal limit in warm enclosures. If your load calculation already sits above roughly 3 A continuous before applying margin, the 90 W rating is borderline and the next wattage class warrants consideration.

Is the Omron S8VS-09024 suitable for powering solenoid valves and contactors directly on the same 24 V rail as the PLC logic?

The S8VS-09024 can supply both logic and inductive field loads from its single 24 VDC output, but best practice in panel design is to distribute the 24 V bus through separately fused branches for logic circuits and inductive loads. Fusing the inductive load branches individually limits fault current from a shorted solenoid or contactor coil to that branch and prevents it from collapsing the supply rail serving the PLC. This is a wiring topology recommendation, not a supply specification limit — the S8VS-09024 does not preclude mixed loads, but individual branch fusing is the correct design practice.

What should I do if the Omron S8VS-09024 is on extended lead time or difficult to source?

The S8VK series is Omron's newer-generation DIN rail switching power supply line and is positioned as the forward-looking platform for new designs — it offers a more compact footprint and higher efficiency than the S8VS. Where S8VS-09024 availability is constrained, a LeadTime.ca specialist can identify the S8VK model that matches the 24 VDC and 90 W class requirement and confirm whether physical and terminal compatibility allows a direct panel substitution. For any critical machine with a running spare requirement, confirming the current form-fit-function substitute before you are in an emergency situation is the lower-risk approach.
