*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.
Note Observe the following restrictions when connecting to a 2-wire sensor.
• Make sure the input power supply voltage does not exceed the ON voltage (19 V) plus the residual volt-
age 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.
ON Response Time
8.0 ms max. (Can be set to between 0 and 32 in the PLC Setup.)
*1
OFF Response Time
8.0 ms max. (Can be set to between 0 and 32 in the PLC Setup.)

neously ON Points

illustrations.)
Insulation Resistance 20 MΩ between external terminals and the GR terminal (100 VDC)
Dielectric Strength
1,000 VAC between the external terminals and the GR terminal for 1 minute at a
leakage current of 10 mA max.

• The input power polarity can be con-
nected in either direction.
• Be sure to wire both pins A9 and A18
(COM0) of CN1, and set the same
polarity for both pins.
• Be sure to wire both pins B9 and B18
(COM1) of CN1, and set the same
polarity for both pins.
• The input power polarity can be con-
nected in either direction.
• Be sure to wire both pins A9 and A18
(COM2) of CN2, and set the same
polarity for both pins.
• Be sure to wire both pins B9 and B18
(COM3) of CN2, and set the same
polarity for both pins.
