Key Parameters and Features
Core Features & Advantages
-
NIST-Traceable Measurement Accuracy: The TREX2 series is calibrated using standards traceable to the National Institute of Standards and Technology (NIST), 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 embedded Bluetooth technology 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 .
-
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 .
-
Automatic Data Synchronization with AMS Device Manager: Field changes made on the communicator automatically synchronize with AMS Device Manager via Wi-Fi or USB. Every change is recorded and time-stamped, maintaining data integrity in the plant's asset management database without manual transcription .
-
Important Note — Basic Module (No Loop Power): The C designation indicates the basic Device Communicator module, which supports HART and FOUNDATION Fieldbus communication on externally powered loops and segments . It lacks loop power capability, current measurement, and advanced loop diagnostics — these features require the Plus (L) module .
Typical Applications
The TREX2CFPKLWP3 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 TREX2CFPKLWP3 indicate?
A: TREX2 = Gen 2 platform; C = Device Communicator (basic) module; F = HART + FOUNDATION Fieldbus applications; P = Li-Ion power module; KL = ATEX/CSA/IECEx IS certifications; W = Wireless (Wi-Fi + Bluetooth); P3 = 3-year Premium Support .
Q2: Does this model include loop power capability?
A: No. The C designation indicates the basic Device Communicator module, which requires the field loop to be externally powered. For loop power capability and NIST-traceable mA measurement, select a model with the L (Plus) module .
Q3: Does the TREX2CFPKLWP3 support FOUNDATION Fieldbus?
A: Yes. 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 FF segment powering .
Q4: Is this device intrinsically safe?
A: Yes. The KL certification includes ATEX, CSA, and IECEx intrinsic safety approvals (including FISCO), 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, and installation DVD. The ValveLink Mobile application is available at no charge once the Trex unit is activated .
Q7: What does Premium Support (P3) include?
A: Premium Support includes standard technical support and software updates, plus extended warranty coverage against manufacturing defects and accidental damage .

Choosing the Right Model
-
For HART + FOUNDATION Fieldbus with basic module and Premium Support: The TREX2CFPKLWP3 is the correct choice for externally powered loops and segments with comprehensive warranty coverage.
-
For loop power and NIST-traceable mA measurement: Select a model with the L (Plus) module instead of C, such as TREX2LFPKLWP3 .
-
For HART-only applications: Choose a model with H instead of F, such as TREX2CHPKLWS3 .
