Battery and Operating Conditions:
A rechargeable Li-Ion battery provides over 8 hours of operation. The device operates in temperatures ranging from -20°C to 55°C (-4°F to 122°F), ensuring reliability in extreme conditions
Communication Modules:
Standard Module: Supports HART and FF protocols with banana-jack terminals for device connections.
Multifunction Module: Adds mA loop measurement (0-22.5 mA resolution) and HART/FF power supply capabilities, eliminating the need for external tools
3. Models and Configurations
The TREX series offers flexible configurations to meet diverse operational needs. Key models include:
TREXLHPKLWS3S: A popular HART-focused model with wireless connectivity (Bluetooth, Wi-Fi, NFC), 3-year standard support, and intrinsic safety certifications. Includes a carrying case and spare accessories
TREXLFPKLWP3: Supports both HART and FF protocols, featuring a multifunction communication module and 3-year premium support for extended warranty and accidental damage coverage
Additional variants are tailored for specific certifications (e.g., ATEX, IECEx) and connectivity options (e.g., wireless or wired).
4. Applications and Benefits
The TREX enhances field productivity across industries such as oil and gas, chemical processing, and power generation.
Valve Configuration and Testing: The integrated ValveLink Mobile app enables inline valve configuration and diagnostics, reducing commissioning time by up to 50%
Loop Diagnostics: Measure 4-20 mA loop currents directly via dedicated terminals, ensuring accurate troubleshooting without disconnecting devices
Predictive Maintenance: Advanced FF segment diagnostics identify issues like cable degradation or power supply instability, enabling proactive maintenance
5. Accessories and Support
Emerson provides a comprehensive suite of accessories and support packages:
Essential Accessories:
Rechargeable Li-Ion Power Module (TREX-0002-1211)
AC/DC adapters for global compatibility (TREX-0003-0011)
Lead sets and magnetic hangers for hands-free operation (TREX-0004-0001)
Software and Licenses: FF license bundles (90-day demo to unlimited subscriptions) and support renewals ensure continuous access to updates and technical assistance
6. Safety and Compliance
The TREX adheres to global safety standards, including FCC Part 15 for electromagnetic compatibility and intrinsic safety certifications for hazardous areas. Its anti-static design minimizes electrostatic risks, while rugged construction ensures longevity in harsh conditions
