*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.

• The input power polarity can be
connected in either direction.
• Be sure to wire both pins 23 and
24 (COM0) of CN1, and set the
same polarity for both pins.
• Be sure to wire both pins 3 and 4
(COM1) of CN1, and set the same
polarity for both pins.
• The input power polarity can be con-
nected in either direction.
• Be sure to wire both pins 23 and 24
(COM2) of CN2, and set the same polar-
ity for both pins.
• Be sure to wire both pins 3 and 4 (COM3)
of CN2, and set the same polarity for
both pins.
