Digital Outputs
All outputs have an identical behaviour. The description here is only for one output (x = 1 to
8 MC100 GPIO).
All switching outputs are represented by solid state relays. OxA occupies one pin of the
switch, OxB the second pin. All outputs are galvanically isolated. The maximum switching
current is 300mA. The maximum applied voltage must not exceed 30V.
Function: Switching the digital outputs
