Digital inputs/outputs

Digital inputs
Properties
● The digital inputs are "high active".
● An open input is interpreted as "low".
● Fixed debouncing setting
● Availability of the input signal for further interconnection
● Simulation mode settable and parameterizable.
● Isolation block by block, set by jumper.

Delay time = 1 to 2 current controller cycles (250 μs)
– inverted and not inverted as a binector output
– as a connector output
– Jumper open: electrically isolated.
The digital inputs function only if a reference ground is connected.
– Jumper closed, non-floating.
The reference potential of the digital inputs is the ground of the Control Unit.
