Honeywell TREXCFPNAWS3S AMS Trex Device Communicator for HART and Foundation Fieldbus

Product Overview

When field technicians need a reliable, portable tool to configure and troubleshoot HART and Foundation Fieldbus devices, the Honeywell TREXCFPNAWS3S AMS Trex Device Communicator delivers. This rugged communicator combines a powerful 800 MHz ARM Cortex A8/NXP processor with a 5.7-inch color VGA resistive touchscreen, enabling clear data visualization even in harsh environments. The TREXCFPNAWS3S is built for industrial mobility, featuring a rechargeable Li-Ion power module that provides over 8 hours of typical use and an IP54 enclosure rating to withstand dust and water splashes.

Technical Specifications

The TREXCFPNAWS3S is engineered for demanding field applications. Key parameters include an 800 MHz ARM Cortex A8/NXP microprocessor, 2 GB NAND internal flash plus 32 GB extended flash memory, and 512 MB DDR3 SDRAM for smooth multitasking. The 5.7-inch color VGA resistive touchscreen (640 x 480 pixel resolution) remains readable in direct sunlight. Operating temperature ranges from -20 to 55°C (-4 to 122°F), and the unit survives a 1-meter drop onto concrete. Weight is approximately 2.9 lbs (1330 grams).

Industry Applications

In oil and gas refineries, the TREXCFPNAWS3S enables technicians to quickly commission and diagnose HART transmitters and Foundation Fieldbus positioners without returning to the control room. Its wireless option reduces cable clutter and speeds up data collection. For chemical plants, the IP54 rating and rugged construction allow safe operation near process areas, while the long battery life supports full-shift field rounds.

Installation and Setup Guidance

Before first use, fully charge the rechargeable Li-Ion power module. Connect the device communicator to the HART or Foundation Fieldbus loop using the appropriate leads. The resistive touchscreen works with gloved hands, simplifying setup in cold environments. Always verify that the communication module is correctly seated and that the wireless radio is enabled if needed. Follow Emerson's quick-start guide for initial configuration.

Maintenance and Reliability

Regularly inspect the touchscreen for cracks and clean it with a soft, dry cloth. Keep the battery contacts clean and store the unit in a dry place when not in use. The TREXCFPNAWS3S is tested to survive a 1-meter drop, reducing downtime from accidental falls. Periodic calibration checks of the communicator's output signals ensure measurement accuracy over time.

Compatibility and Integration

The TREXCFPNAWS3S integrates seamlessly with Emerson AMS Device Manager software and supports HART and Foundation Fieldbus protocols. It works with a wide range of transmitters, valves, and analyzers from multiple manufacturers. The wireless option allows connection to plant networks for remote monitoring and firmware updates.

Selection Guide and Purchasing Advice
