Input conditions
Use the input signal within the following condition ranges.
1 Input voltage when external contact is ON
2 Input current when external contact is ON
3 Input voltage when external contact is OFF
4 Input current when external contact is OFF
5 Tolerable chattering time
6 Input signal hold time
7 Input circuit operation delay time
8 Machine side contact capacity
CAUTION
Do not apply voltages other than those indicated in this manual on the connector. Doing
so may lead to destruction or damage.
Input signal hold time: 40 ms or more is the guideline, and if not held for longer
than the ladder processing cycle time, the input signal will not be recognized.
