Honeywell TREXCHPKLWP1S AMS Trex Device Communicator for HART

Product Introduction

When field device configuration and diagnostics demand a reliable, intrinsically safe communicator, the Honeywell TREXCHPKLWP1S delivers. This AMS Trex Device Communicator combines a powerful 800 MHz ARM Cortex A8/NXP processor with 512 MB DDR3 SDRAM and 2 GB NAND plus 32 GB extended flash memory. Designed for harsh environments, it features an IP54 enclosure rating and survives a 1-meter drop onto concrete. The TREXCHPKLWP1S includes Bluetooth, WiFi, and NFC radios for wireless connectivity, along with a rechargeable Li-Ion power module that provides 8+ hours of typical use. ATEX, CSA (US/Canada), and IECEx intrinsically safe certifications make it suitable for hazardous area applications.

Technical Specifications Breakdown

The 5.7-inch (14.5 cm) color VGA resistive touchscreen offers clear visibility in various lighting conditions. The communicator weighs approximately 2.9 lbs (1330 grams), balancing portability with durability. Its operating temperature range spans -20 to 55°C (-4 to 122°F), ensuring reliable performance in extreme conditions. The memory configuration includes 2 GB NAND internal flash and 32 GB extended flash, providing ample storage for device configurations and firmware updates. The 512 MB DDR3 SDRAM supports smooth multitasking during complex HART device communication.

Industry Applications

In process industries such as oil and gas, chemical, and power generation, the TREXCHPKLWP1S enables technicians to configure, calibrate, and troubleshoot HART field devices directly in the field. Its wireless radios (Bluetooth, WiFi, NFC) allow remote data transfer and integration with asset management systems. The ValveLink Mobile application, available at no charge once the Trex unit is activated, extends functionality for valve diagnostics and configuration. This communicator replaces older handheld terminals, reducing downtime and improving workflow efficiency.

Installation & Setup Guidance

Upon unboxing, connect the AC adapter to charge the Li-Ion power module fully before first use. Use the included USB cable to connect to a PC for firmware updates or data synchronization. The lead set with connectors allows direct connection to HART devices. Attach the hand strap for secure handling during field operations. Activate the Trex unit to access the ValveLink Mobile application and configure wireless settings as per local spectrum approvals. Follow the Quick Start Guide for initial setup procedures.

Maintenance & Reliability

Regularly inspect the touchscreen for cracks or damage, and clean it with a soft, dry cloth. Keep the enclosure seals clean to maintain the IP54 rating. The rechargeable Li-Ion battery provides 8+ hours of typical use; replace it only with an authorized Honeywell power module. The TREXCHPKLWP1S includes Standard Support and coverage against accidental damage during the warranty period. For extended protection, the Premium Support option (1 year) is available. Verify firmware updates periodically to ensure compatibility with new HART device revisions.

Compatibility & Integration

The TREXCHPKLWP1S communicates with HART-enabled field devices from major manufacturers. It integrates with Emerson AMS Device Manager and other asset management platforms via the included USB cable or wireless radios. The device supports FISCO intrinsically safe systems where applicable. For wireless operation, ensure spectrum approval in your country for Bluetooth, WiFi, and NFC. The communicator works with the ValveLink Mobile application for advanced valve diagnostics. No additional software licenses are required for basic HART communication.

Selection Guide & Purchasing Advice
