Technical Data of the Digital Outputs

Parameter		Value
Number of channels per module		8 normally-open relay outputs
Distribution of the channels into groups		2 (4 channels per group)
Connection of the channels O0 to O3		Terminals 10 to 13
Connection of the channels O4 to O7		Terminals 15 to 18
Reference potential for the channels O0 to O3		Terminal 14 (signal name R0..3)
Reference potential for the channels O4 to O7		Terminal 19 (signal name R4..7)
