1440-TPS02-01RB | Allen-Bradley XM-320 Position Measurement Module

Product Description

The Allen-Bradley XM-320 (1440-TPS02-01RB) is a precision position module for turbine supervisory systems, capable of monitoring axial thrust, valve position, differential expansion, and case expansion. It features dual-channel inputs for eddy current transducers, LVDTs, or standard voltage sensors, with isolated 24V power and configurable software settings for sensitivity and voltage range. Outputs include two isolated 4–20 mA channels with buffered signal options. The module supports both DeviceNet and RS-232 communication, providing versatile integration into industrial control networks.
