Product Short Description
Product Introduction: The FC-TSGAS-1624 is a specialized 16-channel gas detection interface module (often deployed as a Field Termination Assembly) within Honeywell’s Safety Manager ecosystem. It bridges toxic and combustible gas detectors with industrial safety and control systems, processing 4–20 mA signals with HART 7 communication. The module automatically recognizes detector types via HART and configures measurement ranges and alarm thresholds accordingly, simplifying system design in multi-hazard facilities such as petrochemical plants.
Description
Technical Specifications:
- Channels: 16 (isolated)
- Input signal: 4–20 mA, HART 7
- Supported gas types: Toxic (e.g., H₂S, CO), combustible (e.g., CH₄)
- Measurement range: 0–100% LEL (combustible), 0–100 ppm (toxic)
- Accuracy: ±0.1% of full scale
- Response time: ≤ 50 ms (signal processing)
- Isolation rating: 3 kVac (channel-to-channel, channel-to-backplane)
- Operating voltage: 24 Vdc ±15%
- Power consumption: Max 20 W (including detector power)
- Operating temperature: -40°C to +70°C
- Protection rating: IP20
- Dimensions: 225 × 108 × 85 mm
- Weight: 0.52 kg
- Mounting: DIN rail (TS35)
- Certification: IEC 61508 SIL 2, ATEX, IECEx, UL 61010
- Compatible interface module: SAI-1620m
Functional Features:
- Dual gas-type support (toxic and combustible) on a single module
- Advanced HART 7 diagnostics — sensor drift, filter contamination, calibration due dates
- Built-in fault detection (open/short circuit, detector failure) with 99% diagnostic coverage
- 3 kVac isolation exceeding industry standards, preventing ground loops and EMI corruption
- Self-diagnostics triggering immediate alerts on channel or module malfunction
Application Scenarios: Refineries, chemical plants, offshore platforms, wastewater treatment facilities, desert pipelines, confined space monitoring. Integrates with Honeywell Safety Manager for ESD sequences and Experion PKS for centralized monitoring.
Installation Requirements: Mount on a 35 mm DIN rail. Pair with the SAI-1620m high-density analog input module for correct processing within Safety Manager. Use the SICC-0001/Lx system cable for controller connection. Terminate field wiring using screw terminals with appropriate torque.
Usage Precautions: The module is SIL 2 certified; SIL 3 deployments require additional architectural measures. It must be paired with SAI-1620m — it cannot operate standalone. HART compatibility depends on the detector’s specific device descriptor.
