Key Parameters and Features
Core Features & Advantages
-
Power the Loop Without External Equipment: The Plus (L) module includes a built-in HART/FOUNDATION Fieldbus power supply with an internal 167 Ω resistor, enabling technicians to power a field device directly from the communicator — even before power and I/O infrastructure is in place. This eliminates the need for external power supplies or loop resistors during bench configuration and field commissioning .
-
NIST-Traceable Measurement for Calibration: The Plus module is calibrated to NIST-traceable standards, with mA measurement accuracy suitable for official calibration activities — not just reference readings. This allows technicians to perform 4-20 mA loop checks and device calibrations with a single handheld tool .
-
Dual Protocol Support (HART + FOUNDATION Fieldbus): The F application code enables both HART and FOUNDATION Fieldbus communication. A Fieldbus Power Plug is included with the Plus module for powering FF segments .
-
Intrinsically Safe for Hazardous Areas: The KL certification includes ATEX, CSA, and IECEx intrinsic safety approvals (including FISCO as applicable), allowing use in Zone 1, Zone 2, Class I Division 1, and Division 2 hazardous locations .
-
Premium Support with Accidental Damage Coverage: The P3 designation includes 3 years of Premium Support, covering technical support, software updates, extended warranty against manufacturing defects, and accidental damage coverage — providing comprehensive protection for the investment .
-
Automatic Data Synchronization: Field changes made on the communicator automatically synchronize with AMS Device Manager via Wi-Fi or USB, maintaining data integrity in the plant's asset management database without manual transcription .
Typical Applications
The TREXLFPKLWP3 is widely used for field device management across process industries:
-
Oil & Gas: HART and FOUNDATION Fieldbus transmitter commissioning and diagnostics in hazardous areas
-
Chemical & Petrochemical: Device configuration and troubleshooting in Zone 1/Division 1 environments
-
Power Generation: Instrument calibration and maintenance in turbine and boiler control loops
-
Pharmaceutical: NIST-traceable calibration of critical process instruments in regulated environments
Frequently Asked Questions (FAQ)
Q1: What does the model number TREXLFPKLWP3 indicate?
A: The breakdown is: TREX = base platform; L = Device Communicator Plus module (loop power, ammeter); F = HART + FOUNDATION Fieldbus applications; P = Li-Ion power module; KL = ATEX/CSA/IECEx IS certifications; W = Wireless (Bluetooth, Wi-Fi, NFC); P3 = 3-year Premium Support .
Q2: Can this model power a device without external power?
A: Yes. The Plus (L) module includes Power the Loop functionality, allowing the communicator to power HART or FOUNDATION Fieldbus devices directly. This is useful for bench configuration and field commissioning before I/O infrastructure is available .
Q3: Does the TREXLFPKLWP3 support FOUNDATION Fieldbus?
A: Yes. The F application code enables both HART and FOUNDATION Fieldbus communication. A Fieldbus Power Plug is included with the Plus module for FF segment powering .
Q4: Is this device intrinsically safe?
A: Yes. The KL certification includes ATEX, CSA, and IECEx intrinsic safety approvals, suitable for Zone 1, Zone 2, Class I Division 1, and Division 2 hazardous areas .
Q5: What is included with the communicator?
A: The base package includes AC adapter, USB cable, lead set with connectors, hand strap, quick start guide, and Resource DVD. The Plus module adds an additional lead set with connectors. The P3 option includes 3-year Premium Support with accidental damage coverage .
Q6: What is the difference between TREX and TREX2?
A: The first-generation TREX (including TREXLFPKLWP3) uses an 800 MHz ARM Cortex A8 processor and Windows Embedded Compact 2013. The TREX2 features a quad-core processor, 64 GB flash memory, and an Android 14 platform with embedded Bluetooth .

Choosing the Right Model
-
For HART + FOUNDATION Fieldbus with Premium Support: The TREXLFPKLWP3 is the correct choice with the Plus (L) module for loop power, NIST-traceable measurement, and accidental damage coverage .
-
For HART + Fieldbus with Standard Support: The TREXLFPKLWS3 offers the same core capabilities with 3-year Standard Support instead of Premium.
-
For HART-only applications: Select a model with H instead of F, such as TREXLHPKLWP3.
