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-440 Master Relay combines 4 relay outputs with XM®bus master capabilities to provide remote, shared and voted relay operation for distributed XM® measurement modules.
The XM-440 offers 4 high power relays suitable for use in most protection applications. The module also supports linking of one or two XM-441 Expansion Relay modules thereby providing a total capacity of up to 12 relays. The module offers “A out of B” style voting logic. The logic, defined uniquely per relay, can be applied to alarm status broadcast from XM measurement modules located anywhere on the DeviceNet bus, including modules of different types. This capability, combined with the individual alarm and relay logic within each measurement module, provides the most versatile and powerful relay logic system available today.
In addition to relay management the XM-440 can signal any number of modules, each of up to four groups, to save their trend/trip data upon activation of any XM-440 relay.
Configuration can be performed remotely via the DeviceNet network, or locally by a PC connected to the integral serial interface. A CD containing the Serial Configuration Utility software and the XM™ Installation and Users Guides is included with every XM™ measurement and relay module sold.
