Input conditions
The input signals must be used within the following condition ranges.
[FCU8-DX731 / FCU8-DX750 / FCU8-DX760 / FCU8-DX761]
[FCU8-DX834]
(*1) Note that "40 ms or more" is a guide of the "Input signal holding time". The input signal is
recognized only when its "ON" state is held longer than the ladder processing cycle time.
(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.
