Internal circuit diagram
*1 NPN/PNP dual type. According to the specifications of the external equipment, ensure proper wiring.
*2 ON voltage/ON current
This is the voltage value or current value that makes the signal go OFF to ON.
The ON voltage value becomes the potential difference between COM IN 1/2/3 and the input terminals.
*3 OFF voltage/OFF current
This is the voltage value or current value that makes the signal go ON to OFF.
The OFF voltage value becomes the potential difference between COM IN 1/2/3 and the input terminals.
*4 Below is a table giving the COM_IN (input common) and input signal connection correspondence.

Important
Chattering countermeasures
• Set the width of input signal filter (5µs to 1000µs) to prevent incorrect input due to chattering.
• Always use non-contact relays (SSR, PLC transistor output) for input signals. If contact relays are used, contact
bounding may turn ON a TIMING input again during measuring.
