Input Circuits
Note: Although the input terminals are electrically insulated from the internal
circuit, do not conduct an insulation resistance test on these terminals.
●
Output Circuits
Note: Although the output terminals are electrically insulated from the internal
circuit, do not conduct an insulation resistance test on these terminals.

Example of Input Connections (Solid-state Switches)
Two-wire Sensors
The count input, counter number selection, reset input, I/O inhibit input, and short input signals are input when the two-wire Sensor turns
ON.

Note: Use the following two-wire Proximity Sensors:
(1) High-level: transistor ON
Switching capacity: 5 mA min. Residual
voltage: 4 VDC max.
(2) Low-level: transistor OFF
Leakage current: 1.5 mA max.
(3) Operating voltage range:
20.4 to 26.4 VDC
We recommend using OMRON E2E-X
