The XM® series from Rockwell Automation is the world’s first machine monitoring and protection system designed as a distributed network of modules deployed on an open standard industrial bus.
The XM-441 Expansion Relay Module is a simple, low cost, solution for adding 4 additional relays to any XM measurement module or to the XM-440 Master Relay module.
The XM-441 offers 4 high power relays suitable for use in most protection applications. When used with the XM-440 Master Relay Module or any of the XM-36x 6-channel measurement modules, the XM-441 can support one additional XM-441 linked to it, providing a total expansion capability of up to 8 additional relays.
The XM-441 is not an intelligent XM module. It must be linked to a standard XM measurement or master relay module in order to function. The module does not utilize the DeviceNet bus. The module simply extends the circuitry of its host module.
This scheme eliminates dependence on the DeviceNet bus and any external wiring providing a level of reliability equivalent to standard integral relays.
No configuration of the XM-441 is required. Setup and operation of the XM-441 is performed by and through its host XM measurement or XM-440 Master Relay module.
