Cj1W-Id232 Dc Input Unit (24 Vdc, 32 Points) - Omron CJ2 CPU UNIT User Manual

Terminal Connections
*1 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 A9 and A18 (COM0), and set the same polarity for both
pins.
• Be sure to wire both pins B9 and B18 (COM1), and set the same polarity for both
pins.
