Key Parameters and Features
Core Features & Advantages
-
Power the Loop and NIST-Traceable Measurement: 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 without external power supplies or loop resistors . It also provides NIST-traceable mA measurement accuracy of ±(0.01% RDG + 2 µA) at 23°C, suitable for official calibration activities in nuclear and pharmaceutical industries .
-
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 .
-
Radar Master Application: The R option code includes the Radar Master app, which brings enhanced echo curve functionality to the field communicator for Rosemount radar level transmitters. Technicians can create tank geometric profiles, tune echo curves, and access trended tank level and alert history directly at the tank .
-
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 .
-
Bluetooth and Wireless Connectivity: The W option includes Bluetooth, Wi-Fi, and NFC radios. Bluetooth connectivity enables wireless communication with Bluetooth-enabled field devices via the AMS Device Configurator App, providing speeds up to 10x faster than traditional HART connections and eliminating the need for hot work permits in hazardous areas .
Frequently Asked Questions (FAQ)
Q1: What does the model number TREX2LFFKLWS1RW 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; S1 = 1-year Standard Support; R = Radar Master app (indicated by the trailing RW in some naming schemes) .
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 .
Q3: Does the TREX2LFFKLWS1RW 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, 64 GB flash memory, NIST-traceable mA measurement, and embedded Bluetooth. The first-generation TREX used an 800 MHz processor, 2 GB NAND flash, and had reference-only measurement accuracy .
Q6: What is included with the communicator?
A: AC adapter, USB cable, lead sets with connectors, hand strap, quick start guide, Foundation Fieldbus Power Plug (FF units), and installation DVD. The ValveLink Mobile application is available at no charge once the Trex unit is activated .

Choosing the Right Model
-
For HART + FOUNDATION Fieldbus with Radar Master: The TREX2LFFKLWS1RW configuration provides loop power, NIST-traceable measurement, and radar level transmitter configuration capabilities.
-
For extended support coverage: Consider a model with S3 (3-year Standard Support) or P3 (3-Year Premium Support) instead of S1.
-
For HART-only applications: Select a model with H instead of F, such as TREX2LHPKLWS3.
