Note
In the relay output version the status of the outputs appears delayed
(<10 ms) due to the switching time of the relays.
Note
High Level at the outputs means relay closed respectively opto
coupler low resistant. Low Level at the outputs means relay open
respectively opto coupler high resistant.
