Installation Notes
Mount in Trusted TMR chassis. Ensure proper grounding for isolation specifications. Use shielded twisted-pair wiring for analog signals. Install external intrinsic safety barriers for hazardous area applications. Maintain 0.5°C/min maximum temperature change rate. Calibrate inputs every 2 years per recommended interval.
Engineering Advantages
Fully triplicated architecture delivers SIL rated safety integrity. 0.5ms update time captures fast process transients. 3.9uA resolution enables precise measurement. Optional line monitoring detects open/short conditions. Sequence of Events with 1ms resolution supports detailed fault analysis. 2.5kV isolation protects against ground loops and transients. Reliable across -5°C to 60°C operating range.
FAQs
Q1: What is the purpose of user defined thresholds?
A1: The 4-off user defined thresholds allow configuration of discrepancy detection levels above which 0x70nn series slice discrepancy faults are raised, enhancing fault diagnosis.
Q2: Does the T8431 require external fusing?
A2: No internal fusing is provided. External fusing is optional and should be applied at the field device or barrier level if required.
Q3: What is the recommended calibration interval?
A3: ICS Triplex recommends a 2 year calibration check interval to maintain specified accuracy. The module's 0.03% calibration accuracy ensures reliable long-term performance.
