POINT I/O Module Data 103
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.
