Product Overview
The Omron C200HW-PA204S is the 30 W class AC power supply for the C200HX/HG/HE and C200HS PLC backplanes. It takes a free-voltage 100-120 VAC or 200-240 VAC input at 120 VA max and converts it to a 5 VDC backplane rail at 4.6 A (including the CPU module draw) and a separate 26 VDC service supply at 0.625 A. The service rail powers a relay row, a sensor rail, or an indicator stack directly from the rack supply so a panel builder can wire the machine without a separate 24 VDC PSU. The S suffix is the distinguishing feature -- the bare C200HW-PA204 has the same 5 VDC output but no service rail.
The 26 VDC service rail
The 26 VDC output is sized to feed the C200H-CT021 and C200H-CT002 high-speed counter units (which need 0.625 A at 26 VDC) plus a typical 8-to-16-point relay row. The supply is rated 0.3 A continuous and 0.8 A with the +17% / -11% line-voltage compensation -- the 0.8 A figure is the practical budget on a 200-240 VAC line, the 0.3 A figure is the worst-case 100-120 VAC line. Pick the C200HW-PA209R instead when a 5 VDC 9 A / 26 VDC 1.3 A (45 W) PSU is needed for a deeper rack with several high-speed counters.
The PA204 family split
Pick C200HW-PA204C for the 100-240 VAC free-voltage AC input. Pick C200HW-PA204 for the bare 30 W PSU without the service rail. Pick C200HW-PA204R when an external indicator needs the SPST-NO RUN contact (250 VAC 2 A resistive / 24 VDC 2 A resistive). Pick C200HW-PD024 (24 VDC input, 5 VDC 4.6 A) or C200HW-PD025 (24 VDC input, 5 VDC 6 A) when the cabinet has a 24 VDC rail instead of mains. The PA204S slides into the leftmost slot of a C200HW-BC031 (3-slot) / BC051 (5-slot) / BC081 (8-slot) / BC101 (10-slot) CPU backplane.
Before ordering
Confirm the input supply is 100-120 VAC or 200-240 VAC (the bare C200HW-PA204 is 100-120 / 200-240 only -- pick the PA204C for a 100-240 VAC free-voltage cabinet). Confirm the 26 VDC service current budget (0.3 A at 100-120 VAC vs 0.8 A at 200-240 VAC with the +17%/-11% line-voltage compensation). Confirm the existing backplane is a C200HW-BCxx1 (not a C200H-BC031 legacy 3-slot) -- the 10-slot high-output PA209R needs the C200HW-BC101-V1 backplane.

- Small C200HS or C200H-Alpha machine panel with a relay row on the 26 VDC service rail
- Existing C200H-PS221 cabinet where the bare PA204 needs an upgrade to the 24 V service-rail version
- OEM skid with 8-10 C200H-series I/O slots that needs a 5 VDC + 24 VDC service from one PSU
- Legacy packaging machine where the original PSU is EOL and the PA204S is the documented replacement
Buying Checklist
- Pick C200HW-PA204S for a 30 W AC PSU with the 26 VDC service rail for relay / sensor / counter power.
- Pick C200HW-PA204 instead when the application does not need the 26 VDC service rail and a smaller wire count is fine.
- Pick C200HW-PA204R instead when an external indicator needs the SPST-NO RUN contact (250 VAC 2 A resistive).
- Pick C200HW-PA204C for the 100-240 VAC free-voltage AC input cabinet (single global SKU).
- Pick C200HW-PA209R for a 45 W PSU with 9 A at 5 VDC and 1.3 A at 26 VDC for a deeper rack with several counters.
- Pick C200HW-PD024 or PD025 when the cabinet is fed with 24 VDC instead of mains (4.6 A or 6 A at 5 VDC).

FAQ for C200HW-PA204S
What is the difference between C200HW-PA204, PA204S, and PA204R?
All three are 30 W, 4.6 A at 5 VDC, 100-120 / 200-240 VAC PSUs. The bare C200HW-PA204 has no service rail. The PA204S adds a 0.625 A at 26 VDC service supply for relay / sensor / counter power. The PA204R is the PA204S plus a SPST-NO RUN contact (250 VAC 2 A resistive) for an external RUN indicator. Pick the PA204S for the 26 VDC service rail without the RUN contact; pick the PA204R for the RUN contact without a separate relay module.
What is the 26 VDC service supply on the PA204S used for?
The 26 VDC output feeds the C200H-CT021 and C200H-CT002 high-speed counter units (which need 0.625 A at 26 VDC) and a typical 8-to-16-point relay row. The actual available current is 0.3 A continuous or 0.8 A with the +17%/-11% line-voltage compensation on a 200-240 VAC line. It is the same supply as the older C200H-PS221 and the modern C200HW-PA204S / PA209R -- the only difference is the maximum draw. Pick the PA209R instead for 1.3 A at 26 VDC.
Can I use the PA204S on a 100-240 VAC free-voltage cabinet?
No. The C200HW-PA204S is the split-voltage 100-120 / 200-240 VAC SKU. For a 100-240 VAC free-voltage AC cabinet, pick the C200HW-PA204C (100 VA max, 4.6 A at 5 VDC, 0.625 A at 26 VDC). The PA204C is the right pick for global single-SKU inventory; the PA204S is the regional split-voltage pick for North America / Japan / Europe cabinets fed from a known 100-120 or 200-240 VAC supply.
Does the PA204S work in a C200H or CS1 rack?
Yes, with the right backplane. The PA204S slides into the leftmost slot of any C200HW-BC031 / BC051 / BC081 / BC101 CPU backplane. It also works in a C200H-BC031 / BC051 / BC081 legacy 3/5/8-slot backplane. For a CS1 / CS1D CPU rack, pick the CS1W-PA205R (25 W) or CS1D-PA207R (35 W) instead -- the C200HW PSU does not fit a CS1 / CS1D backplane. For a CJ / CJ2 rack, pick the CJ1W-PA202 / PA205R or CJ1W-PD022 / PD025 instead.
