Honeywell TREXCHPKLWS1 AMS Trex Device Communicator

Technical Specifications Breakdown

Key parameters for the TREXCHPKLWS1 are listed below for quick reference:

Installation and Setup Guidance

Before using the communicator, ensure the battery is fully charged. The device ships with a standard support plan for one year, which covers software updates and technical assistance. To connect to a HART instrument, use the appropriate communication cables and ensure the instrument is powered. The communicator will automatically detect the HART protocol and display the device menu. For wireless operation, configure the network settings through the device’s interface. Always verify that the device is in the correct operating mode before connecting to a live loop.

Maintenance and Reliability

To keep the communicator performing reliably, inspect the device periodically for physical damage, especially the display and the connector ports. Clean the screen with a soft, dry cloth. Avoid exposing the device to extreme temperatures or direct sunlight for extended periods. The rechargeable Li-Ion battery should be charged regularly; if you notice a significant drop in battery life, contact AutoDCSTech for a replacement. The device’s rugged design is intended for industrial use, but regular care will extend its service life.

Field-Proven Configuration for HART Device Management

This AMS Trex Device Communicator combines the Base Trex Platform with a Device Communicator communication module, a HART application, and a rechargeable Li-Ion power module. The result is a dependable tool that helps reduce loop commissioning time and keeps maintenance operations moving efficiently.

The TREXCHPKLWS1 is built for technicians who require both performance and safety. Its wireless radio option allows you to connect to instruments and access documentation without being tethered to a wired network. The device is certified ATEX, CSA (US/Canada), and IECEx Intrinsically Safe, including FISCO where applicable, so you can carry it into explosive atmospheres with confidence. With an 800 MHz ARM Cortex A8/NXP microprocessor and 512 MB DDR3 SDRAM, the communicator responds quickly to menu navigation and HART commands.

Built for HART Instrumentation in the Field

The HART application is the core of this communicator. It lets you communicate with HART-enabled transmitters, positioners, and analyzers to read process variables, change configuration parameters, and perform loop tests. The wireless capability means you can move freely around the plant while staying connected to the device under test. This is especially useful when working on elevated platforms or in congested areas where a wired connection would be impractical.

Intrinsically Safe Certifications for Hazardous Areas

The TREXCHPKLWS1 carries ATEX, CSA (US/Canada), and IECEx Intrinsically Safe certifications, including FISCO where applicable. That means you can use it in Zone 1/Division 1 environments without needing a hot work permit. The rechargeable Li-Ion power module is designed to meet the strict energy limits required for intrinsic safety, so you get the runtime you need without compromising safety.

Compatibility and Integration

The TREXCHPKLWS1 is part of the AMS Trex family, which integrates with Emerson’s AMS Device Manager software. This allows you to upload configuration data, document field device changes, and generate reports. The wireless option enables connectivity to plant networks, so you can synchronize data without physical cable connections. The device runs on Windows Embedded Compact 2013, providing a familiar interface for technicians.

Troubleshooting and Common Issues

If the communicator fails to power on, check the battery charge level and connections. If the screen is unresponsive, perform a soft reset by holding the power button for 10 seconds. For communication errors, verify that the HART loop is properly powered and that the communicator is connected to the correct terminals. If the wireless connection drops, move closer to the access point or check the network configuration. For persistent issues, consult the user manual or contact AutoDCSTech for technical support.
