Attention: 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.
