*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 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.
Terminal Connec-
tions
CN1 (OUT) CN2 (IN)
• Be sure to wire both terminals 23 and 24 (COM0) of CN1.
• Be sure to wire both terminals 3 and 4 (COM1) of CN1.
• Be sure to wire both terminals 21 and 22 (+V) of CN1.
• Be sure to wire both terminals 1 and 2 (+V) of CN1.
• When wiring, pay careful attention to the polarity of the exter-
nal power supply. The load may operate incorrectly if polarity
is reversed.
• Be sure to wire both pins 23 and 24 (COM2) of
CN2, and set the same polarity for both pins.
• Be sure to wire both pins 3 and 4 (COM3) of
CN2, and set the same polarity for both pins.
• When wiring, pay careful attention to the polarity
of the external power supply. The load may oper-
ate incorrectly if polarity is reversed.
