C200HW-PA204S

Product information

Product Overview

The rack-mounted Power Supply Unit that feeds a C200HW I/O rack or a CS1 CPU rack. The distinguishing feature of the “S” variant is a 24 VDC service output (0.8 A) that the plain PA204 does not have — power for input devices and sensors without a separate DIN-rail supply.

This page is written for buyers and maintenance engineers sourcing C200HW-PA204S as a new part or a replacement. Every specification below is taken from Omron’s own published data for this model; no third-party or estimated figures are used, and where Omron publishes two different figures or two variants for the same parameter, both are shown.

Omron catalogue designation: C200HW Power Supply Unit (C200H / CS1 rack). Official catalogue code for this model: C200HW-PA204S.

Why Buyers Specify This Model

The 24 V service output is the reason to choose the S variant

Compared with the C200HW-PA204, the PA204S adds a 0.8 A, 24 VDC output. In a panel this usually removes one small DIN-rail power supply and the associated wiring — and it means sensor and input-device power is lost and restored with the PLC, which simplifies fault finding.

The 30 W total is shared, not per output

Omron specifies a maximum total power of 30 W across the 5 V, 26 V and 24 V outputs. Filling the 5 V budget with I/O cards leaves correspondingly less for the other two rails. Omron’s ordering information carries a current-consumption table per unit so the budget can be checked before the rack is specified — use it rather than assuming all three rails can be loaded to their individual limits at once.

Inrush current sets the breaker, not the running current

30 A for up to 8 ms on a 200–240 V supply will trip a breaker chosen only on 120 VA of running load. Select the external breaker and fuse against the inrush figure, with margin for a hot restart where the thermistor has not cooled.

Wide-range input

85 to 132 VAC / 170 to 264 VAC covers both nominal 100–120 V and 200–240 V networks without a selector. Where the local supply is nominal 220 V and drifts, check the upper figure (264 V) against your worst case rather than the nominal 240 V.

The 0.8 A, 24 VDC output is a service supply: Omron’s own instruction sheet for this Unit states it is for input devices, photoelectric switches and sensors — not for driving output devices. Keep output loads on a separate supply.

Lifecycle and availability

This is a long-established Unit in Omron’s CS/C200H power supply family. Omron’s CS-series catalogue documents it as a catalogue item, and its full performance data is published in the same document as the CS1 CPU Units.

For installations running C200HX/HG/HE or CS1 hardware, the practical question is not whether the product exists but whether a specific unit can be secured for the date you need it. Give us the quantity and the required date and we will answer against that position, including the option of a functionally identical alternative from the same family where one exists.

Availability, condition of supply and lead time are quoted per enquiry because they depend on quantity and on where the goods are held. We do not publish stock or lead time as fixed figures on this page. Tell us the quantity and the date you need it and we will answer with a firm position rather than a promise.

Official Documentation

The specifications on this page are taken from Omron’s own documents. You can download the source document directly:

• SYSMAC CS Series Catalogue (Cat. No. P047-E1-14) — https://edata.omron.com.au/eData/PLCs/CS1/P047-E1-14.pdf

Full technical detail — wiring diagrams, derating curves, installation requirements and the complete ordering tables — is in that document. If you need a specific figure we do not show here, ask and we will point you to the exact page rather than paraphrase it.

Ordering This Part

Send us the full catalogue number C200HW-PA204S (and the model number C200HW-PA204S you are replacing), the quantity, your delivery address and the date you need the goods. If it is a replacement, attach a photograph of the existing unit’s nameplate — it removes any doubt about the revision, the output type or the supply voltage, which are the three things that most often cause a wrong part to be shipped.

We do not publish stock, condition or lead time as fixed figures here, because they change: they are quoted per enquiry against the quantity and date you actually need. If a machine is down, say so and give us the required window — that is the information that determines how we source it.

Frequently Asked Questions

PA204, PA204S or PA204R — which do I need?

All three are 4.6 A / 5 V, 30 W Units in the same family. The S adds the 0.8 A 24 VDC service output; the R adds a relay contact (RUN output) rather than the service supply. Ask for the one whose difference matches what your panel is missing — the base 5 V capacity is the same on all three.

Can it supply input sensors directly?

Yes, up to 0.8 A at 24 VDC, which is exactly what this output is documented for. It is not intended to drive output devices such as solenoid valves or relay coils.

Is the C200HW rack still supported?

C200HW I/O racks are the C200H-generation expansion racks that CS1 CPU Units can also drive through CS1W-CN311/311-B2 connecting cables; Omron lists the C200HW Power Supply Units alongside the CS1 family in its CS-series catalogue. If you are maintaining an existing C200HX/HG/HE or CS1 installation, this Unit is the documented spare.

What should I send with the enquiry?

The rack it goes into (C200HX/HG/HE rack or CS1 rack) and the total load on each of the three outputs. That is enough to confirm the 30 W budget with margin.
