Honeywell TREXCHPNAWP3S AMS Trex Device Communicator with HART

Technical Specifications Breakdown

Key parameters for the TREXCHPNAWP3S are listed below for quick reference:

The TREXCHPNAWP3S is designed for technicians who work across multiple plants and need a single tool to handle diverse HART devices. In a typical chemical plant, you might use it to commission a new pressure transmitter, verify loop wiring, or troubleshoot a smart valve positioner. The wireless capability allows you to connect to the device without physical cable attachment, which is especially useful in hard-to-reach or hazardous areas.

The 800 MHz processor and 2GB NAND flash ensure fast boot-up and responsive navigation through device menus, reducing the time spent on each calibration task. The 32 GB extended flash provides ample storage for configuration files and firmware updates, so you can carry an entire library of device definitions in your pocket.

Installation & Setup Guidance

Before using the TREXCHPNAWP3S, ensure the battery is fully charged. The rechargeable Li-Ion power module can be charged using the provided adapter. To connect to a HART device, use the appropriate HART cables (not included) and attach them to the device's communication terminals. Power on the communicator and select the HART application from the home screen. The device will automatically poll the network to detect connected devices. For wireless operation, enable the radio option and pair the communicator with your plant's wireless gateway. Always follow your plant's safety procedures when connecting to live process loops.

Maintenance & Reliability

To maintain reliable performance, keep the device's firmware up to date. Emerson periodically releases updates that add new device descriptions and improve functionality. Clean the touchscreen with a soft, dry cloth. Inspect the charging contacts and battery for signs of wear. The Li-Ion battery should retain most of its capacity for several years, but if you notice shorter run times, contact AutoDCSTech for a replacement. Avoid exposing the device to extreme temperatures or direct sunlight for prolonged periods.
