Description
This relay output Module is designed to switch pilot lamps, valves, and relay coils up to 5 A per
output. The relays can drive loads ranging from 20 to 110 Vdc or from 20 to 250 Vac. Two screw
terminals are reserved for each relay output. Two groups are separated with individual common
power grounds.
