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 resistor, enabling technicians to power a field device directly from the communicator — even before power and I/O infrastructure are in place. This eliminates the need for external power supplies or loop resistors during bench configuration and field commissioning.
-
NIST-Traceable Measurement for Calibration: Unlike the first-generation Trex, the TREX2 Plus module is calibrated to NIST-traceable standards, ensuring that mA measurement and sourcing accuracy is 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. When ordered with the Plus (L) module, a Fieldbus Power Plug is included for powering FF segments. This makes the communicator suitable for plants with mixed protocol environments.
-
Bluetooth Connectivity and Modern Platform: The TREX2 runs on a quad-core processor with Android 14 OS and includes embedded Bluetooth for wireless communication with Bluetooth-enabled field devices via the AMS Device Configurator App. The modern platform delivers faster response times and an intuitive mobile-device-like user experience.
-
Radar Master and WirelessHART Provisioning Apps: The R and W option codes add Radar Master for radar level transmitter configuration and WirelessHART Provisioning for fast, secure wireless network setup. These applications extend the communicator's utility beyond basic device configuration.
-
Intrinsically Safe for Hazardous Areas: The KL certification includes ATEX, CSA, and IECEx intrinsic safety approvals (including FISCO), allowing use in Zone 1, Zone 2, Class I Division 1, and Division 2 hazardous locations.
Typical Applications
The TREX2LFPKLWS3RW is widely used for field device management across process industries:
-
Oil & Gas: HART and FOUNDATION Fieldbus transmitter commissioning, valve diagnostics, and radar level configuration in hazardous areas
-
Chemical & Petrochemical: Device configuration, loop troubleshooting, and calibration 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 TREX2LFPKLWS3RW indicate?
A: TREX2 = Gen 2 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; S3 = 3-year Standard Support; R = Radar Master App; W = WirelessHART Provisioning App.
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 TREX2LFPKLWS3RW 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 the difference between TREX2 and the first-generation TREX?
A: The TREX2 features a quad-core processor, Android 14 OS, 64 GB flash memory, NIST-traceable mA measurement, and embedded Bluetooth. The first-generation TREX used Windows Embedded Compact and had reference-only measurement accuracy.
Q6: What is included with the communicator?
A: AC adapter, USB cable, lead sets with connectors, hand strap, Foundation Fieldbus Power Plug (FF units), and carrying case (S option).

Choosing the Right Model
-
For HART + FOUNDATION Fieldbus with radar and wireless provisioning: The TREX2LFPKLWS3RW is the most comprehensive configuration.
-
For HART-only applications: Select TREX2LHPKLWS3 (Plus module) or TREX2CHPKLWS3 (basic module).
-
For FOUNDATION Fieldbus without radar/wireless apps: TREX2LFPKLWS3 offers the same core FF capability without the additional applications.
