Honeywell TREXCHPNAWP3S AMS Trex Device Communicator with Wireless & 3-Year Support

Product Overview

When field device configuration and diagnostics become a bottleneck in plant operations, the Honeywell TREXCHPNAWP3S AMS Trex Device Communicator delivers a powerful solution. This base Trex platform integrates a Device Communicator communication module specifically for HART applications, ensuring reliable communication with smart field devices. With a rechargeable Li-Ion power module and wireless radio options, this model reduces the need for frequent battery swaps and cabling, directly lowering maintenance costs and improving technician productivity.

Technical Specifications Breakdown

Processor and Memory Performance

The TREXCHPNAWP3S runs on an 800 MHz ARM Cortex A8/NXP microprocessor, paired with 512 MB DDR3 SDRAM. This combination enables fast boot times and responsive operation when navigating device menus or running diagnostics. The 2 GB NAND internal flash plus 32 GB extended flash provides ample storage for device descriptions, configuration files, and firmware updates, minimizing downtime spent on data management.

Operating System and Display

Windows Embedded Compact 2013 offers a familiar, stable environment for industrial applications. The 640 x 480 pixel display delivers clear visibility of device parameters and trends, even in challenging lighting conditions. This clarity reduces operator errors and speeds up commissioning tasks, translating to lower labor costs per device.

Power and Connectivity

The rechargeable Li-Ion power module supports extended field use without tethering to a power source. Wireless capability (radio option W) allows technicians to communicate with devices from a distance, reducing the need for physical access in hazardous or hard-to-reach areas. This feature alone can cut travel time and improve safety, offering a clear return on investment.

Industry Applications

Process Plant Commissioning and Maintenance

In oil refineries or chemical plants, the TREXCHPNAWP3S enables technicians to configure HART transmitters, valve positioners, and analyzers directly in the field. The wireless option reduces the need to run temporary cables, speeding up loop checks and reducing commissioning time by up to 30%. This efficiency directly lowers project costs.

Remote Asset Monitoring

For remote wellheads or pipeline stations, the device communicator's long battery life and wireless connectivity allow technicians to perform diagnostics without frequent site visits. The 32 GB extended flash stores historical device data for trend analysis, helping predict failures before they cause unplanned shutdowns. This predictive capability reduces maintenance spend by avoiding emergency repairs.

Installation and Setup Guidance

Before first use, fully charge the Li-Ion power module using the provided charger. Insert the SD card (if needed) into the slot to load additional device descriptions. Power on the unit and connect to the HART device using the standard leads. For wireless operation, enable the radio in the settings menu and pair with the plant’s wireless network. Always verify the device is configured for the correct HART revision to avoid communication errors.

Maintenance and Reliability

The TREXCHPNAWP3S is built for rugged field use, but regular care extends its service life. Keep the touchscreen clean and free of debris. Inspect the charging port and battery contacts periodically for corrosion. The rechargeable Li-Ion battery typically lasts several years; replace it when runtime drops significantly. Following these simple steps prevents unexpected downtime and ensures the device remains a cost-effective tool for years.

Selection Guide and Purchasing Advice

When ordering the TREXCHPNAWP3S, confirm that your plant’s HART devices are compatible with the Device Communicator communication module. This model includes a carrying case (S option) for safe transport and storage. For ongoing support, the 3-year standard support plan (P3) covers software updates and technical assistance.
