*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.

• 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 pins A9 and B9 (COM0 (0
V)) of CN1.
• Be sure to wire both pins A10 and B10 (+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 A9 and B9 (COM1) of
CN2, and set the same polarity for both pins.
