Honeywell TREXCHPKLWS1 AMS Trex Device Communicator for HART

Product Overview

When field device configuration and diagnostics become critical in hazardous environments, the Honeywell TREXCHPKLWS1 delivers a powerful, intrinsically safe solution. As an AMS Trex Device Communicator, this unit combines an 800 MHz ARM Cortex A8/NXP microprocessor with 512 MB DDR3 SDRAM and 2 GB NAND plus 32 GB extended flash memory, running Windows Embedded Compact 2013 on a 640 x 480 pixel display. Designed for demanding industrial applications, the TREXCHPKLWS1 supports HART communication and includes wireless radio capability, making it a versatile tool for technicians working in process plants, refineries, and offshore platforms.

Technical Specifications Breakdown

The TREXCHPKLWS1 is built on the Base Trex Platform with a Device Communicator communication module. It features a rechargeable Li-Ion power module for extended field use. The product certifications include ATEX, CSA (US/Canada), and IECEx Intrinsically Safe, covering FISCO as applicable, ensuring safe operation in explosive atmospheres. The wireless radio option (W) enables cable-free connectivity for remote configuration and data transfer. Standard support is included for one year (S1).

Industry Applications

In oil and gas facilities, the TREXCHPKLWS1 allows technicians to configure and troubleshoot HART field devices such as pressure transmitters and valve positioners without entering the control room. Its intrinsic safety certifications (ATEX, CSA, IECEx) make it suitable for Zone 0/1 and Division 1 hazardous areas. In chemical plants, the wireless capability reduces the need for physical cable connections, speeding up loop checks and commissioning. The rugged design and long battery life from the Li-Ion power module support all-day field use.

Installation & Setup Guidance

To begin using the TREXCHPKLWS1, ensure the Li-Ion power module is fully charged. Power on the device and connect to the HART loop via the provided leads. The Windows Embedded Compact 2013 interface provides intuitive menus for device discovery and configuration. For wireless operation, enable the radio module and pair with a compatible access point. Always verify the device is configured for the correct HART revision and device descriptor before making changes.

Maintenance & Reliability

Regularly inspect the TREXCHPKLWS1 for physical damage, especially the display and connector ports. Keep the Li-Ion power module charged and store the unit in a clean, dry environment when not in use. The 32 GB extended flash memory ensures ample storage for device configurations and logs. For long-term reliability, follow Emerson’s recommended calibration schedule for the HART communication module.

Compatibility & Integration

The TREXCHPKLWS1 is part of the AMS Trex family and integrates seamlessly with Emerson’s AMS Device Manager software. It supports HART protocol devices from multiple manufacturers, including those from Honeywell, Rosemount, and others. The wireless radio option allows connection to plant networks for remote monitoring and data synchronization.

Selection Guide & Purchasing Advice

Before purchasing the TREXCHPKLWS1, verify that your facility requires intrinsic safety certifications (ATEX, CSA, IECEx) and HART application support. The wireless option is ideal for plants with existing wireless infrastructure. For current availability and lifecycle status, contact BluePLC Industrial.
