CJ1W-ID232 DC Input Unit (24 VDC, 32 Points)
* The ON response time will be 20 μs maximum and OFF response time will be 400 μs maximum even if the response times are set to 0 ms due
to internal element delays.
Note: Observe the following restrictions when connecting to a 2-wire sensor.
• Make sure the input power supply voltage is larger than the ON voltage (19 V) plus the residual voltage of the sensor (approx. 3 V).
• Use a sensor with a minimum load current of 3 mA min.
• Connect bleeder resistance if you connect a sensor with a minimum load current of 5 mA or higher.

• The input power polarity can be connected in either direction.
• Be sure to wire both pins 23 and 24 (COM0), and set the same polarity for both pins.
• Be sure to wire both pins 3 and 4 (COM1), and set the same polarity for both pins.
• The signal names of the terminals are the device variable names.
The device variable names are the names that use "Jxx" as the device name.
