• The input power polarity can be connected in either direction.
• Be sure to wire both pins 23 and 24 (COM0), and set the same polarity for both pins.
• Be sure to wire both pins 3 and 4 (COM1), and set the same polarity for both pins.
* The ON response time will be 15 s maximum and OFF response time will be 90 s 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 is larger than the ON voltage (19 V) plus the residual voltage of the sen-
sor (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.
