CW Green Tech Announces In-Stock Availability of Emerson AMS Trex Series Communicators

Four Popular Models Ready to Empower Efficient Industrial Field Maintenance and Calibration
[China, April 27, 2026] – CW Green Tech, a high-quality supplier in the industrial automation sector, today announced that the company has four popular models of Emerson AMS Trex series device communicators in stock, including the TREXCHPNAWS1S, TREXLFPKLWS3S, TREXLHPNAWS3S, and TREXLHPKLWS3S. This product portfolio offers Chinese industrial users a more timely and convenient solution for field device maintenance.

Rich In-Stock Matrix to Meet Diverse Application Needs

The four AMS Trex device communicators currently in stock at CW Green Tech cover different protocol configurations and application scenarios:

[TREXCHPNAWS1S](https://www.cwlyautomation.com/product/11332.html "TREXCHPNAWS1S"): Supports HART protocol, equipped with a standard communication interface and a carry case, suitable for device configuration and diagnostics in conventional industrial environments.

[TREXLHPKLWS3S](https://www.cwlyautomation.com/product/11329.html "TREXLHPKLWS3S"): Supports HART protocol, equipped with a multifunctional configuration interface, and holds ATEX, CSA, and IECEx intrinsic safety certifications for safe operation in hazardous areas — an ideal choice for the petroleum and chemical industries.

[TREXLHPNAWS3S](https://www.cwlyautomation.com/product/11330.html "TREXLHPNAWS3S"): Supports HART protocol, equipped with a configuration interface, and includes three years of standard support and software update services, balancing performance and cost efficiency.

[TREXLFPKLWS3S](https://www.cwlyautomation.com/product/11331.html "TREXLFPKLWS3S"): Supports both HART and FOUNDATION Fieldbus (FF) protocols, equipped with a multifunctional communication module and intrinsic safety explosion-proof certification. It can simultaneously handle the commissioning of both HART and FF bus devices, making it a versatile "all-rounder" for field engineers tackling complex working conditions.

All the above models are built on Emerson's unified high-performance hardware platform, featuring a 5.7-inch color VGA resistive touchscreen, an 800 MHz ARM Cortex A8 processor, a rechargeable lithium-ion battery module, and an IP54 protection rating. They can operate reliably in harsh environments ranging from -20°C to 55°C.

All-in-One Capability, From Configuration and Diagnostics to Compliant Calibration

Emerson AMS Trex series device communicators can connect to more than 2,500 types of field instruments from Emerson and third-party manufacturers, serving industries such as power generation, petrochemicals, pharmaceuticals, and food and beverage.

At the end of 2025, Emerson officially released the fully upgraded AMS Trex 2nd Generation Device Communicator, achieving three major breakthroughs in hardware performance, calibration capability, and connectivity: memory eight times that of the previous generation and a quad-core processor for significantly faster operation response; the addition of NIST-traceable calibration certification, enabling the device to be used for formal instrument calibration and helping users streamline their on-site tool inventory; and the addition of Bluetooth HART communication for wireless integration with mobile devices, expanding field application scenarios.

The in-stock models available from CW Green Tech include both new and legacy versions, allowing users to flexibly choose based on project requirements and technical specifications.

In-Stock Advantage Shortens Project Lead Times

In industrial projects, equipment lead times are often a critical factor affecting project schedules. CW Green Tech's centralized stocking aims to help users avoid long lead times and respond to emergency maintenance and new line construction needs with a "ship from stock" model. A company representative stated: "We fully understand the dual demands of field engineers for device reliability and rapid response. Through routine stocking of the AMS Trex series, we can ensure that customers receive the tools they need in the shortest possible time, ensuring smooth project execution."
