 The input power polarity can be connected in either direction. Be sure to wire both pins 23 and 24 (COM0) of CN1, and set the same polarity for both pins. Be sure to wire both pins 3 and 4 (COM1) of CN1, and set the same polarity for both pins. The signal names of the terminals are the device variable names. The device variable names are the names that use “Jxx” as the device name. |

* The ON response time will be 120 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 is larger than 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.
