Rockwell Automation 1440-SPD02-01RB XM-220 Dual Speed Module - Manual (Page 10)

Publication GMSI10-UM004B-EN-P - May 2010
2 Introduction
The module includes a single on-board relay (expandable to five), two 4-20mA
outputs, and a buffered output for each input. A third buffered output is
available when the module is functioning in the single redundant channel
mode. This buffered output signal corresponds to the active input signal so
that the machine speed can be accurately tracked regardless of which of the
redundant sensors is active.
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.
The module can be configured remotely via the DeviceNet network, or locally
using a serial connection to a PC or laptop. Refer to Chapter 3 for a list of the
configuration parameters.
