*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 does not exceed the ON voltage (19 V) plus the residual volt-
age 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.
z CJ1W-ID232 DC Input Unit (24 VDC, 32 Points)
Terminal Connections
• 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.
