Emerson TREXLHPKLWS3S handheld device communicator

Emerson TREXLHPKLWS3S handheld device communicator

TREXLHPKLWS3S is an Emerson AMS Trex series intrinsically safe handheld device communicator (controller), equipped with Plus enhanced communication module, supports HART protocol, built-in loop power supply function, and comes with 3 years of official software upgrade and technical support services. TREXLHPKLWS3S is mainly used for intelligent instrument debugging in industrial sites. It can provide circuit power supply, parameter configuration, range setting, circuit diagnosis, mA signal measurement, valve diagnosis, and fault troubleshooting for intelligent instruments such as pressure/temperature/liquid level transmitters, valve positioners, and flow meters; Collecting device diagnostic information, device data can be uploaded wirelessly to the AMS device management system, suitable for on-site instrument maintenance in explosion-proof hazardous areas.

Product features

1. Intrinsic safety explosion-proof certification, which can be directly used in Zone 1 hazardous explosion-proof areas such as chemical and petrochemical industries, meeting the explosion-proof standards of multiple countries around the world.
2. The Plus enhancement module comes with a built-in loop power supply function, which does not require a 24V power supply on site. It can directly supply power to HART instruments and independently complete offline instrument debugging.
3. A 5.7-inch color resistive touch screen that can still be operated while wearing protective gloves; The screen backlight is adjustable, allowing for clear viewing of both bright and dark scenes.
4. Integrated mA current measurement, high-precision reading of 4-20mA signals, can quickly troubleshoot instrument circuit disconnection, short circuit, and load abnormalities.
5.  Built in a large number of device DD driver libraries, compatible with Rosemount, Fisher, Yokogawa EJA、 The vast majority of brands such as Chuanyi use HART smart instruments.
6.  Supports Wi Fi and Bluetooth wireless transmission, and debugging records and device diagnostic files can be synchronously uploaded to the AMS device management system to achieve digital management of device assets.
7. The sturdy casing is IP54 protected, dust-proof and splash proof, and has passed a 1-meter drop test, making it suitable for rough on-site operations such as workshops and outdoors.
8.  Large capacity lithium batteries, with a typical working time of over 8 hours per full charge, meet the requirements for on-site maintenance work throughout the day.
9.  Equipped with ValveLink valve diagnostic function, it can perform stroke, friction, and valve internal health diagnosis on intelligent valve positioners, and predict valve faults in advance.
10. Equipped with a 3-year official standard service, including firmware updates, DD library upgrades, remote technical support, and extended device lifecycle.
11. Equipped with trend recording function, real-time monitoring of circuit current changes and capturing intermittent fault signals.
