* The ON response time will be 20 s maximum and OFF response time will be 400 s 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 terminals 3 and 4 (COM0
(0 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 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.
