Relay Output Modules
The relay output modules consist of 1734-OW2 and 1734-OW4 2-relay output
modules and 1734-OX2 4-relay output modules. Features of the 1734-OW2 and
1734-OW4 relay modules include the following:
•
Type A Normally Open relays
•
Sink or source a current with respect to power or return
•
Contact outputs isolated from each other
•
Each output rated 5…240V dc/V rms at 2 A (current is load dependant)
•
Autobaud (will match baud of existing devices on the network)
•
Sequential auto addressing
Features of the 1734-OX2 relay modules include the following:
•
Two Form C isolated (normally open; normally closed)
electromechanical relays
•
Sink or source a current with respect to power or return
•
Contact outputs isolated from each other
•
Each output rated 5…240V dc/V rms at 2 A (current is load dependant)
•
Autobaud (will match baud of existing devices on the network)
•
Sequential auto addressing
I/O messages are sent to (consumed) and received from (produced) these
POINT I/O modules. These messages are mapped into the processor memory.
