Product Overview
The Omron CJ1W-CIF11 is an RS-422A converter for the SYSMAC CS/CJ-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 adapter plugs directly onto the built-in RS-232C port of a CS1G, CS1H, CJ1G, CJ1H, CJ1M or CJ2 CPU and converts the signal to RS-422A or RS-485. Maximum cable run is 50 m. A 5-pin terminal block carries the differential pair and shield; an on-board DIP switch selects 4-wire RS-422A or 2-wire RS-485, toggles the termination resistor, and sets the RS control mode.
Supply is 5 VDC, drawn from pin 6 of the RS-232C connector, so no separate power feed is needed. Current draw is 40 mA max. The CJ1W-CIF11 is the external converter; the CP1W-CIF11 is the option board for CP1L / CP1H. They are not interchangeable. For an isolated adapter, pick the NT-AL001.
Key Features
- External RS-232C to RS-422A / RS-485 adapter for CS1, CJ1, CJ1M and CJ2 series PLCs
- Plugs directly onto the CPU's built-in RS-232C port; no separate power feed
- Maximum cable run 50 m, on-board DIP switch for 4-wire / 2-wire mode and termination
- 5 VDC supply (drawn from RS-232C pin 6), 40 mA max, not isolated
- SKU: CJ1W-CIF11
- Series: Omron SYSMAC CS/CJ option, RS-422A converter
- Voltage: 5 VDC
Best-Fit Applications
- Host Link serial link from a CS1H-CPU@@H on a stamping press to a panel-mount HMI 30 m across the cell in 4-wire RS-422A
- Modbus-RTU polling of four V1000 inverters on a CJ1M-CPU22 in 2-wire RS-485 with the termination resistor ON at the master
- Field-service spare carried in the toolbox so a retrofit CS/CJ job needing RS-422A does not need a different CPU
Buying Checklist
- Pick the CJ1W-CIF11 for an external RS-232C to RS-422A/485 adapter that mounts directly onto the RS-232C port of a CS/CJ CPU.
- Pick the CP1W-CIF11 instead when the cabinet uses a CP1L or CP1H CPU and the option board slot is available -- the CJ1W-CIF11 does not fit a CP1-series CPU.
- Pick the NT-AL001 instead when the cabinet needs an isolated RS-422A adapter for a run longer than 50 m on the same RS-232C port.

FAQ for CJ1W-CIF11
What is the Omron CJ1W-CIF11 used for?
It converts the built-in RS-232C port on a CS1G, CS1H, CJ1G, CJ1H, CJ1M or CJ2 CPU to RS-422A or RS-485. That extends the serial cable to 50 m and lets the CPU run Host Link, Modbus-RTU or NT Link against a remote HMI, inverter or barcode reader.
Can the CJ1W-CIF11 be used with a CP1L or CP1H CPU?
No. The CP1L and CP1H take the CP1W-CIF11 / CP1W-CIF12-V1 option board, not the CJ1W-CIF11 adapter. The CJ1W-CIF11 plugs onto the RS-232C port of a CS/CJ-series CPU.
What is the maximum cable run for the CJ1W-CIF11?
50 m, matching the spec on the Omron ia.omron.com family/2062 page. The CJ1W-CIF11 is not isolated, so for longer runs on the same RS-232C port pick the NT-AL001 isolated adapter.
