66 IB-1501269-F
(a) Outline of digital signal input circuit
Both 24V common and 0V common connections are allowed in the digital signal input circuit.
Follow the wiring diagram below for each type.
Input circuit
Input conditions
The input signals must be used within the following condition ranges.
(Note) Input signal holding time: The guide is 40ms or more. The input signal will not be
recognized unless it is held for the ladder processing cycle time or longer.
(E) : External signal, (I):Internal signal
(Note) Set the number of DI points that are simultaneously turned ON to be less than half of the total
points.
If many points are set to be simultaneously turned ON, operation panel I/O unit may be
deteriorated due to the heat.
