8502-BI-DP MTL Bus interface module

The Emerson TREXLHPKLWS3 Device Communicator is an intrinsically safe and explosion-proof communicator designed for debugging and validation of HART protocol instruments, as well as diagnostics and commissioning of other field instruments such as FOUNDATION Fieldbus.

Here are some of the key features of the Emerson TREXLHPKLWS3 device communicator:

Robust diagnostics: The communicator has robust diagnostics for a wide range of hardware, device connections, supported applications, and diagnostics that can run on devices, 4-20mA current circuits, or FOUNDATION Fieldbus network segments [1].

Equipment power supply module: communicator built-in equipment power supply module, no additional DC power supply, just connect the communicator and the instrument that needs to be powered to debug and verify the equipment, speed up the configuration process.

Explosion-proof performance: The communicator has intrinsic safety explosion-proof certification and can be used in various hazardous area locations.

Technical specifications:

Display: 5.7-inch color VGA resistive touch screen, 640x480 pixels.

Microprocessor: 800 MHz ARM Cortex A8 / NXP.

Operating system: Windows Embedded Compact 2013

Internal flash: 2GB NAND and 32GB expansion flash.

RAM: 512 MB DDR3 SDRAM[2][3].

Communication module: The standard communication module C has HART terminals and field bus (FF) terminals, and the multi-function communication module F adds two power terminals with protocol power supply functions and an external ammeter mA terminal [1].

Portability and protection: The communicator comes with a carry case S to protect the instrument from falling and breaking the screen [1].

Fast configuration: In the new project, the TREXLHPKLWS3S communicator loop power function allows HSRT protocol devices to be configured in the field without waiting for power or I/O to be in place, and transmitter configuration is no longer the final step in the new project [1].

In addition, the communicator has several other functions, such as valve configuration, test synchronization, monitoring status and alarms, performing step tests, running valve signatures, viewing and saving diagnostic tests, etc. [3].
