Product Overview
The Omron CP1W-CIF12-V1 is an isolated RS-422A/485 serial option board for CP-series PLCs, manufactured by Omron Corporation. Hengyixin Automation stocks this controller option board in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.
The board drops into the option slot on the CPU's top face and adds one RS-422A or RS-485 port. The port is electrically isolated from the PLC, which is what lets cable runs reach 500 m — the non-isolated CP1W-CIF11 stops at 50 m. Baud rates run from 1.2 to 115.2 kbps, and the board draws 0.04 A from the CPU's 5 V rail. Supported modes include Host Link, 1:N NT Link, Serial PLC Link, Modbus-RTU Easy Master, and no-protocol.
It fits CP1L, CP1H, CP2E N-type, and CP1E N30/N40/N60 and NA20 CPUs. It does not fit CP1E E-type, N14, N20 or the slim N30S/N40S/N60S units — those have no option slot. Pick the CP1W-CIF11 instead for short in-cabinet runs where isolation isn't needed.
Key Features
- Isolated RS-422A/485 option board for CP1L, CP1H, CP2E and CP1E N-type PLCs
- 500 m maximum cable run — ten times the non-isolated CP1W-CIF11
- One port, 1.2 to 115.2 kbps, draws 0.04 A from the CPU 5 V rail
- Will not fit CP1E E-type, N14, N20 or slim N30S/N40S/N60S CPUs (no option slot)
- SKU: CP1W-CIF12-V1
- Series: Omron CP1W option board family
Best-Fit Applications
- Modbus-RTU link from a CP1E-N30DR-A to a bank of pump inverters 300 m away across a water treatment site
- Serial PLC Link between two CP1L-EM30DT-D CPUs in separate cabinets where the shared 0 V would otherwise carry noise
- Retrofit on a CP1H-X40DR-A kiln line, replacing a CP1W-CIF11 whose 50 m limit was being exceeded
Buying Checklist
- Pick the CP1W-CIF12-V1 when the RS-422A/485 run is longer than 50 m or the two ends sit on different grounds.
- Pick the CP1W-CIF11 instead for a short non-isolated run inside one cabinet at lower cost.
- Pick the CJ1W-CIF11 instead to convert an existing RS-232C port to RS-422A/485 without using the option slot.

FAQ for CP1W-CIF12-V1
What is the Omron CP1W-CIF12-V1 used for?
It adds one isolated RS-422A or RS-485 port to a CP-series PLC. Typical jobs are Modbus-RTU polling of inverters and meters, Serial PLC Link between two CPUs, and 1:N NT Link to NS or NB touch panels.
CP1W-CIF12-V1 vs CP1W-CIF11 — what is the difference?
Isolation and cable length. The CIF12-V1 is isolated and rated for 500 m; the CIF11 is not isolated and stops at 50 m. The slot, the port count and the baud rates are the same. Pay for the CIF12-V1 when the cable leaves the cabinet.
Does the CP1W-CIF12-V1 work with CP1E?
Yes, on the N30, N40, N60 and NA20 CPUs, which have an option slot. It does not work on CP1E E-type, N14, N20 or the slim N30S/N40S/N60S units, because those have no option slot at all.
What is the maximum cable length for the CP1W-CIF12-V1?
500 m, per Omron's CP-series option board table. That is the total trunk length from the board to the far end of the RS-422A/485 line. For longer distances add a repeater or move the link to Ethernet.
