Honeywell TREXCHPNAWS1 AMS Trex Device Communicator with HART and Wireless

Product Overview

When field device configuration and diagnostics demand a rugged, portable solution, the Honeywell TREXCHPNAWS1 delivers. As an AMS Trex Device Communicator, this unit combines a Base Trex Platform with a Device Communicator communication module, HART application, rechargeable Li-Ion power module, wireless capabilities, and standard support for one year. Its 800 MHz ARM Cortex A8/NXP microprocessor and 512 MB DDR3 SDRAM ensure responsive operation, while the 640 x 480 pixel display provides clear data visualization. Designed for industrial environments, the TREXCHPNAWS1 helps reduce downtime and improve maintenance efficiency, offering a cost-effective approach to device management.

Technical Specifications Breakdown

The TREXCHPNAWS1 features an 800 MHz ARM Cortex A8/NXP microprocessor, providing ample processing power for HART device communication and data logging. Internal flash memory includes 2GB NAND and 32GB extended flash, enabling storage of device configurations and firmware updates. The unit runs on Windows Embedded Compact 2013, a reliable operating system for field instruments. RAM of 512 MB DDR3 SDRAM supports multitasking and smooth operation. The 640 x 480 pixel display, a 5.7-inch color VGA resistive touchscreen, offers durability and readability in bright conditions. These specs translate to faster device setup, reduced configuration errors, and lower labor costs over the product lifecycle.

Industry Applications

In process plants, the TREXCHPNAWS1 excels at commissioning and troubleshooting HART field devices. Technicians use its HART terminals with two banana plugs and selectable internal resistance of 250 Ohm or 500 Ohm to communicate with transmitters and valves. For wireless needs, the unit includes Bluetooth 2.1 with a range up to 10 m, Wi-Fi 802.11 b/g with a range up to 33 m, and active NFC up to 20 cm. This wireless flexibility reduces cable management costs and speeds up data collection. In refineries and chemical facilities, the rechargeable Li-Ion battery provides over 8 hours of normal operation with a 3 to 4 hour charge time, minimizing downtime and extending field usability. By integrating these capabilities, the TREXCHPNAWS1 lowers total cost of ownership through improved technician productivity and reduced travel for diagnostics.

Installation & Setup Guidance

Setting up the TREXCHPNAWS1 involves charging the battery fully before first use, which takes 3 to 4 hours. Connect to HART devices using the two banana plug terminals, selecting the appropriate internal resistance (250 Ohm or 500 Ohm) via the device menu. For wireless communication, enable Bluetooth or Wi-Fi in the operating system settings. The micro USB 2.0 connector allows data transfer to a PC, but always disconnect the USB cable from the Trex before connecting to a device to avoid conflicts. Ensure the unit is within 10 m for Bluetooth or 33 m for Wi-Fi of the target device for reliable communication. These steps help avoid configuration errors and reduce setup time, directly impacting project costs.

Maintenance & Reliability

To maintain the TREXCHPNAWS1, regularly inspect the rechargeable Li-Ion battery for capacity degradation. The battery normally lasts over 8 hours per charge; if runtime decreases, plan for replacement to avoid field interruptions. Keep the touchscreen clean and free of debris to ensure accurate touch response. Periodically update the device firmware via the extended flash memory to support new HART device revisions. These simple practices extend the communicator's service life, reducing replacement frequency and overall equipment expenditure. The robust design, combined with standard support for one year, provides peace of mind and predictable maintenance costs.

Compatibility & Integration

The TREXCHPNAWS1 is designed for HART device communication, supporting both point-to-point and multidrop configurations. It works with a wide range of HART-enabled transmitters, actuators, and analyzers from various manufacturers. The wireless options—Bluetooth 2.1, Wi-Fi 802.11 b/g, and active NFC—allow integration with asset management systems and mobile devices for remote diagnostics. The unit's Windows Embedded Compact 2013 OS enables compatibility with standard configuration software. When selecting accessories, verify that the communication module matches your device protocols. BluePLC Industrial offers this model along with compatible accessories to streamline your procurement process.

Selection Guide & Purchasing Advice

Before purchasing the TREXCHPNAWS1, confirm your device communication requirements: this model supports HART applications only. Verify that the wireless radio options (FCC, CE, RED, and IC certified Bluetooth 2.1 and Wi-Fi 802.11 b/g) meet your site's regulatory needs. The standard support period is one year; consider extending support for critical deployments.
