Honeywell TREXCHPNAWS3S AMS Trex Device Communicator for HART

Product Overview

When field device configuration becomes a bottleneck in plant operations, the Honeywell TREXCHPNAWS3S AMS Trex Device Communicator delivers a robust solution. This handheld communicator combines a powerful 800 MHz ARM Cortex A8/NXP microprocessor with a Windows Embedded Compact 2013 operating system, enabling efficient HART device setup and diagnostics. Part of the Trex platform, the TREXCHPNAWS3S is designed for engineers who need reliable, portable access to smart field instruments.

Technical Specifications Breakdown

The TREXCHPNAWS3S integrates several key modules that define its performance. The communication module (C) supports HART applications (H), making it suitable for configuring and troubleshooting HART-compatible field devices. A rechargeable Li-Ion power module (P) provides cordless operation, while the wireless option (W) enables remote connectivity. The device features 2GB NAND and 32 GB extended flash memory, plus 512 MB DDR3 SDRAM, ensuring smooth multitasking. The 640 x 480 pixel display offers clear visibility for menus and diagnostics. Standard support for 3 years (S3) and a carrying case (S) are included.

Industry Applications

In process industries such as oil and gas, chemical, and power generation, the TREXCHPNAWS3S addresses the pain point of time-consuming field device configuration. Engineers can wirelessly connect to HART instruments, reducing walk times and increasing uptime. The rechargeable battery supports long shifts without power interruptions. For maintenance teams, the device's 32 GB extended flash provides ample storage for device configurations and documentation, streamlining compliance and reporting.

Installation & Setup Guidance

Setting up the TREXCHPNAWS3S involves charging the Li-Ion power module fully before first use. Ensure the wireless option is enabled in the system settings to connect to plant networks. The device boots into Windows Embedded Compact 2013, where users install the AMS Trex software suite. For HART communication, connect the device communicator module to the field device loop using standard leads. Verify the connection by checking the device status on the 640 x 480 pixel display.

Maintenance & Reliability

To maximize the TREXCHPNAWS3S lifespan, periodically inspect the rechargeable battery for capacity degradation. Keep the carrying case clean and store the device in a dry environment. The 3-year standard support plan ensures access to firmware updates and technical assistance, reducing downtime risks. Regular calibration of the communication module is not required, but verify HART signal integrity during annual audits.

Compatibility & Integration

The TREXCHPNAWS3S integrates seamlessly with Emerson's AMS Device Manager software, supporting HART protocol devices from multiple manufacturers. The wireless option allows connection to plant Wi-Fi networks for data synchronization. The device is compatible with standard HART field instruments, including pressure, temperature, and flow transmitters. No additional gateways are needed for basic HART communication.

Selection Guide & Purchasing Advice

Before purchasing the TREXCHPNAWS3S, verify that your plant's HART devices are supported by the AMS Trex platform. Confirm the wireless infrastructure is available if using the W option. The carrying case is included, but consider spare batteries for extended field use. BluePLC Industrial offers the TREXCHPNAWS3S with full warranty and support, ensuring you receive a genuine Honeywell product.
