The module includes a single on board relay, expandable to five, two 4-20mAoutputs, and a buffered output for each input. A third buffered output is availablewhen the module is functioning in the single redundant channel mode. Thisbuffered output signal corresponds to the active input signal. It is provided so thatconnected devices, including other XM modules, can be assured of always receivinga valid speed signal - as long as at least one of the two redundant speed inputs isfunctioning properly.

Configuration can be performed either locally or remotely via the DeviceNet network.Local configuration is provided by a simple, intuitive Serial Configuration Utilityexecuting on a PC connected to the modules serial communications port. Remoteconfiguration can be performed from any networked PC executing either any standard DeviceNet configuration software, or the XM specific configuration tool

included in Rockwell Software?s RSMACC Enterprise Online software system The XM-220 can operate stand alone, or it can be deployed on a standard or dedicated DeviceNet network where it can provide real-time data and status information to other XM modules, PLCs, distributed control systems (DCS), and Condition Monitoring Systems.
