Product Overview
The Omron CJ1W-ID201 is the small-size DC input unit for the CJ-series PLC family. manufactured by Omron Corporation. Hengyixin Automation stocks this controller in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports. Specifications on this page were checked against Omron's CJ-series basic I/O Unit specification table.
It drops onto one slot of a CJ1M, CJ2M, or CJ-expansion rack and gives eight 24 VDC digital inputs wired through a removable screw-terminal block. Each input has its own common, so eight different ground sources can be connected without tying commons together, and all eight points can be ON at once without derating.
The CJ1W-ID201 ships from Xiamen with full datasheet documentation. Set the input response time (0 to 32 ms in 1 ms steps) in the CPU's I/O setup so noise on long cable runs does not cause false triggers.
Key Features
- 110 g typical body, 110 g max
- 80 mA max internal draw from the CJ backplane
- Rated DC 12 to 24 V (operating DC 10.2 to 26.4 V)
- 10 mA typical per input at DC 24 V; 2.4 kOhm input impedance
- SKU: CJ1W-ID201
- Series: CJ1W-ID201
- Voltage: 12 TO 24 V
- I/O: 8 I/O
Best-Fit Applications
- Adding a handful of extra 24 V inputs to a CJ1M / CJ2M rack that ran out of CPU points
- Spare-channel card kept on the shelf for cabinet expansion without touching the existing wiring
- Low-voltage DC signal pickup from proximity sensors, photo eyes, and limit switches in a panel
Buying Checklist
- Pick CJ1W-IA111 for AC 100-120 V inputs or CJ1W-IA201 for AC 200-240 V inputs.
- Pick CJ1W-ID201 for 8 DC inputs on a small CJ rack with removable screw-terminal wiring.
- Pick CJ1W-ID211 for 16 points instead when you need more density on the same slot count.

FAQ for CJ1W-ID201
Is CJ1W-ID201 PNP or NPN?
Either. The ID201 has eight independent commons, so each input can be wired for PNP (sourcing) or NPN (sinking) by how the common is tied. Most modern 24 V panels wire the inputs as NPN (sink to the PLC) by tying the common to +24 V, but PNP (source to the PLC) by tying the common to 0 V works the same way without any DIP switch.
How fast is the CJ1W-ID201 input response?
Default 8.0 ms in both directions, selectable from 0 to 32 ms in 1 ms steps from the CPU's I/O setup. With the response set to 0 ms, the ON time drops to a floor of about 20 us and the OFF time to about 400 us. For high-speed counting where every microsecond matters, step up to the CJ1W-ID212 (16-pt, 15 us ON / 15 us OFF) or the CJ1W-CT021 high-speed counter unit.
How much current does the CJ1W-ID201 draw from the CJ backplane?
About 80 mA maximum from the 5 VDC bus on the CJ rack, just to run the input logic. The actual sensor current is sourced from the field supply, not the backplane, so the ID201 does not draw 24 VDC from the rack. Total rack budget is the sum of all module draws -- 80 mA here, plus what the rest of the rack uses.
