*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.
Terminal Connections
CN1 (OUT) CN2 (IN)
• When wiring, pay careful attention to the polarity
of the external power supply. The load may oper-
ate incorrectly if polarity is reversed.
• Be sure to wire both terminals 3 and 4 (COM0
(+V)) of CN1.
• Be sure to wire both terminals 1 and 2 ((0 V)) of
CN1.
• When wiring, pay careful attention to the polarity of
the external power supply. The load may operate
incorrectly if polarity is reversed.
• Be sure to wire both pins 3 and 4 (COM1) of CN2,
and set the same polarity for both pins.
