Internal circuit diagram
*1 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 and the input terminals.
*2 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 and the input terminals.
*3 Below is a table giving the COM_IN (input common) and input signal connection correspondence.

Chattering countermeasures
• The sensor is designed with functions to deal with chattering, but if chattering of 100 s or more occurs, incorrect
input due to chattering cannot be prevented. (Input signal changes of less than 100 s are ignored. The input signal
is applied when the same level is maintained for 100 s or longer.)
• 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.
