10.6.1: Overview
The Relay Output Module consists of four Latching Relay Outputs. In Normal Mode, the device
accepts commands to control the relays. Relay output modules are triggered by limits programmed
with the Communicator EXT software. See the Communicator EXT User Manual for details on
programming limits.
The Nexus® 1262/1272 unit does not supply power for the Relay Output modules. A power source
is required. See Section 10.2 for power and communication details.
The Modbus Map for the Relay Output Module (and operating details) can be found in the Modbus
Communicating Output Modules Manual.
Each latching relay will hold its state in the event of a power loss.
