Input conditions
The input signal must be used within the conditions shown below.
Input voltage when external contact is ON
Input current when external contact is ON
Input voltage when external contact is OFF
Input current when external contact is OFF
Tolerable chattering time
Input signal hold time
Input circuit operation delay time
Machine side contact capacity
Input voltage when external contact is ON
Input current when external contact is ON
Input voltage when external contact is OFF
Input current when external contact is OFF
Tolerable chattering time
Input signal hold time
Input circuit operation delay time
Machine side contact capacity
(Note) The input signal hold time 40ms or more is a reference. The input signal will not be
recognized unless the input signal is held for longer than the ladder process cycle time.
