Description
This combo module with DC Inputs and relay outputs is designed to drive relays, pilot lamps, valves and
other loads up to 5 A and senses the DC input Voltage and converts them to a True or False logic Signal.
It has 1 group of 8 optically isolated 24/48/60 Vdc inputs (M-201, M-204, M-207/M-202, M-205, M-208/M203, M-206, M-209) and 4 relay outputs (M-201 to M-209). The relays can drive loads ranging from 24 Vdc
to 110 Vdc or from 24 to 250 Vac. Two screw terminals are reserved for each relay output, though they are
isolated between them.

Note:
To increase the service of life of the contacts and to protect the module from potential reverse voltage damage,
externally connect a clamping diode in parallel with each inductive DC Load or connect and RC snubber circuit
with each inductive AC Load.
