IB-1501613-A
<Input conditions>
Set the input signal within the range as shown in the conditions below.
[FCU8-DX731/FCU8-DX750/FCU8-DX760/FCU8-DX761]
[FCU8-DX834]
(*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.
(E): External signal, (I): Internal signal
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.
