<Input conditions>
Set the input signal within the range as shown in the conditions below.
1 Input voltage at external contact ON
2 Input current at external contact ON
3 Input voltage at external contact OFF
4 Input current at external contact OFF
5 Input resistance
6 Tolerable chattering time (T1)
7 Input signal holding time (T2)
8 Input circuit operation delay time (T3 and T4)
9 Machine side contact capacity
(*1) Input signal holding time: The guide is 40 ms or more. The input signal is recognized only when its "ON" state is held lon-
ger than the ladder processing cycle time.
