Emerson TREXLHPKLWS3S AMS Trex Device Communicator

Intrinsically Safe Certifications

• The KL certification covers ATEX, CSA (US/Canada), and IECEx intrinsic safety standards. This allows safe use in explosive atmospheres containing gas or dust.
• FISCO approval applies for Foundation Fieldbus intrinsically safe applications. Users can connect to FISCO power supplies in Zone 1 hazardous areas.
• Rugged construction meets strict safety requirements for petrochemical and mining sites. The device prevents ignition sources during normal operation.

Processor and Operating Platform

• An 800 MHz ARM Cortex A8/NXP microprocessor drives all operations. This processor delivers fast screen updates and quick command responses.
• Windows Embedded Compact 2013 provides a stable and responsive user interface. Technicians navigate menus without frustrating delays or freezes.
• 512 MB DDR3 SDRAM supports running the HART Application alongside diagnostic tools. Multitasking remains smooth even with large device descriptions loaded.

Memory and Display Specifications

• Internal flash includes 2GB NAND plus 32GB extended storage capacity. This holds years of device configurations, logs, and software updates.
• The 640 x 480 pixel display shows detailed device menus and process variables. High contrast ensures readability in both bright sunlight and dark plant areas.
• Brand: Emerson delivers precision communication tools trusted by automation professionals worldwide.
• Model: TREXLHPKLWS3S represents the AMS Trex Device Communicator with intrinsically safe certifications and complete accessories.

Communication and Application Features

• The Device Communicator Plus module (L) enhances connection stability with HART instruments. It supports advanced diagnostic commands and faster data transfer.
• HART Application (H) provides full access to device variables and configuration parameters. Users can perform trim adjustments, loop tests, and status checks.
• Wireless radio option (W) enables remote collaboration and software updates. Experts can view the screen remotely to assist with troubleshooting.
• Rechargeable Li-Ion Power Module (P) delivers all-day power for field use. The included adapter charger replenishes the battery quickly between shifts.

Environmental and Signal Performance

• Operating temperature range spans -20°C to 55°C for harsh field conditions. The device functions reliably in extreme heat or freezing environments.
• IP54 rating protects against dust ingress and water spray from any direction. This suits outdoor installations and washdown areas in process plants.
• Electromagnetic immunity prevents interference from nearby motors, drives, and radios. Signal integrity remains high even in electrically noisy environments.
• Frequency response accurately captures HART protocol communication signals. The device resolves 1-2 mA/sec changes for precise loop diagnostics.
• Measurement resolution displays HART primary variables up to five decimal places. This matches the native resolution of smart transmitters in the field.

Frequently Asked Questions

• Q: What hazardous area zones does the TREXLHPKLWS3S certification cover?
  A: ATEX, CSA, and IECEx certifications cover Zone 0, 1, and 2 gas groups as well as Zone 20, 21, 22 dust areas. FISCO adds Foundation Fieldbus capability.
• Q: Does the carrying case fit all accessories included in this package?
  A: Yes, the custom case accommodates the communicator, HART leads, charger, battery, and documentation. It includes foam cutouts to secure each item.
• Q: Can I use this communicator with WirelessHART adapters in the field?
  A: The device supports HART communication through physical connections. Wireless option refers to the communicator's own connectivity, not WirelessHART network.
• Q: How long does the battery last on a full charge during active use?
  A: The rechargeable Li-Ion module provides up to 8 hours of continuous HART communication. Standby time extends significantly between field tasks.
• Q: What is the difference between Device Communicator Plus and standard module?
  A: The Plus module (L) offers faster data transfer and supports additional diagnostic commands. It improves performance with complex modern field devices.
• Q: Does the device include linearization curves for non-linear transmitters?
  A: Yes, the HART Application applies manufacturer-specific linearization tables. This ensures accurate reading of level, flow, and temperature variables.
