The XM-320 position module accepts input from linear variable differential transformers (LVDT), noncontact eddy current probes, rotary cam (valve) potentiometers or any voltage output position measurement devices. With two 4-20mA outputs and a single onboard relay, expandable to five, the XM-320 position module is a complete position monitoring system in a small, simple, easily installed, easily maintained package.

The XM-320 can operate stand alone, with no interface to higher-level control systems or interactive user interfaces. It can also be deployed on a standard or dedicated DeviceNet network where it can provide real-time data and status information to other XM^® modules, PLC’s, DCS and Condition Monitoring Systems.

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.
