Emerson AMS Trex Device Communicator

Designed for comfortable, one-handed operation in the field, the Trex communicator is packaged in an evenly-balanced form factor with a rugged hand strap so you can easily hold it, even when working in tight spaces. With built-in Bluetooth, USB, and WiFi connectivity, move data to and from the communicator using the connectivity option that is most convenient.

The AMS Trex is an intrinsically safe HART and Foundation Fieldbus device communicator. It allows technicians to configure, isolate, diagnose, and repair problems while devices continue to run using the Power the Loop function and on-board milli-ampmeter.
