Honeywell FC-TSGAS-1624
Product introduction
The FC-TSGAS-1624 is a specialized gas detection interface module from Honeywell, engineered to serve as a critical link between gas detection sensors and industrial safety/control systems. As a core component of Honeywell’s gas monitoring ecosystem, this module is designed to process signals from 16 isolated channels of gas detectors, converting raw sensor data into actionable insights for both safety and process management.
FC-TSGAS-1624 excels in monitoring both toxic and combustible gases, leveraging HART 7 communication to not only capture 4-20 mA measurement signals but also retrieve diagnostic data from smart detectors. Its SIL 2 certification ensures it meets the rigor of safety-critical applications, enabling seamless integration with Honeywell’s Safety Manager for emergency shutdown (ESD) sequences, while compatibility with Experion PKS allows for centralized monitoring. Whether deployed in oil refineries, chemical plants, or wastewater treatment facilities, FC-TSGAS-1624 provides real-time gas concentration monitoring, predictive maintenance alerts, and rapid fault response—forming a vital safety barrier for personnel and assets.
Core advantages and technical highlights
Dual gas type support: FC-TSGAS-1624 is uniquely designed to handle both toxic and combustible gas detectors, eliminating the need for separate modules for different gas types. This versatility simplifies system design in facilities where multiple gas hazards exist—for example, a petrochemical plant monitoring both H₂S (toxic) and methane (combustible). The module automatically recognizes detector types via HART, configuring measurement ranges and alarm thresholds accordingly, reducing setup complexity.
Enhanced safety integrity: With SIL 2 certification per IEC 61508, FC-TSGAS-1624 ensures reliable performance in safety loops. It features built-in fault detection (e.g., open/short circuits, detector failures) and self-diagnostics with 99% coverage, triggering immediate alerts if a channel or the module itself malfunctions. This level of integrity is critical in applications like confined space monitoring, where a missed gas leak could lead to fatal exposures or explosions.
Advanced HART diagnostics: Beyond measuring gas concentrations, FC-TSGAS-1624 uses HART 7 to access detailed detector health data—such as sensor drift, filter contamination, or calibration due dates. For instance, it can identify a CO detector with a failing sensor element while still monitoring CO levels, enabling scheduled maintenance before a complete failure. This proactive approach reduces false alarms and ensures detectors remain reliable when needed most.
Robust isolation and ruggedness: The module’s 3 kV AC isolation exceeds industry standards, preventing ground loops and electrical interference that could corrupt gas measurements or trigger false alarms. This is particularly valuable in industrial environments with long cable runs from detectors to control rooms. Combined with its wide operating temperature range (-40°C to +70°C) and resistance to vibration/EMI, FC-TSGAS-1624 maintains performance in harsh conditions, from offshore platforms to desert pipelines.
Typical application scenarios
In oil and gas production facilities, FC-TSGAS-1624 monitors wellheads and processing areas by connecting to 16 Honeywell XNX gas detectors. It tracks methane (combustible) and H₂S (toxic) levels, with 4-20 mA signals converted to real-time concentrations displayed on Experion PKS. If methane exceeds 50% LEL or H₂S exceeds 10 ppm, the module triggers Safety Manager to activate ventilation systems and sound alarms via relay outputs. HART diagnostics also alert maintenance teams to replace detector sensors approaching end-of-life, preventing unplanned downtime.
Chemical manufacturing plants utilize FC-TSGAS-1624 in storage tank farms, where it monitors volatile organic compounds (VOCs) and toxic gases like chlorine. The module’s fast response time (<50 ms) ensures rapid detection of leaks during tank filling operations, enabling immediate shutdown of transfer pumps via Safety Manager. Its 3 kV isolation protects against electrical noise from nearby pumps, ensuring stable readings even in electrically noisy environments.
Wastewater treatment plants deploy FC-TSGAS-1624 to monitor biogas (methane) and hydrogen sulfide in digesters. The module connects to intrinsically safe detectors, processing signals to prevent explosive methane buildup and protect workers from H₂S exposure. HART data on detector calibration status is integrated into the plant’s CMMS, streamlining maintenance schedules. The module’s rugged design withstands the high humidity and corrosive fumes common in wastewater facilities, ensuring long-term reliability.

Installation, commissioning and maintenance instructions
Installation preparation: Before installing FC-TSGAS-1624, ensure the DIN rail is mounted in a dust-free, explosion-proof enclosure (if in hazardous areas) with ambient temperature between -40°C and +70°C. Use a torque wrench set to 1.2 Nm to secure the module. Verify the 24 V DC power supply is isolated, fused (3A), and capable of supplying 20 W (including detector power). Use shielded twisted-pair cables (minimum 0.75 mm²) for detector connections, grounding the shield at the module end to minimize EMI. Route cables separately from high-voltage lines, and label each channel with the corresponding detector location.
Maintenance suggestions: For FC-TSGAS-1624, perform weekly checks of status LEDs to verify power, communication, and channel health. Use Honeywell’s Gas Monitor Software monthly to run HART diagnostic scans, checking for sensor drift, filter blockages, or detector calibration due dates. Calibrate the module annually using a certified gas standard and signal generator to ensure accuracy. Inspect cable connections quarterly for corrosion or looseness, reterminating with stainless steel lugs if needed. If a channel fails, isolate it via software and replace the module with a Honeywell-certified spare to maintain SIL 2 integrity. Back up configuration settings to a secure device to simplify replacement.
