FC-TSGAS-1624 Temperature Gas Sensing Module Industrial Control 16-Channel 24V High Precision

1. SIL 2-Certified Hazardous Gas Monitoring Solution​

The Honeywell FC-TSGAS-1624 is a high-density gas detection module engineered for continuous monitoring of toxic and combustible gases in industrial safety systems requiring SIL 2 compliance per IEC 61508. Featuring ​16 configurable input channels, this device supports ​electrochemical, ​catalytic bead, ​IR, and ​PID sensors​ with ​​±1% accuracy​ across ​0–100% LEL / 0–500ppm ranges. Its ​stainless steel 316L housing​ provides ​IP66/IP68 protection​ against dust, water immersion (3m depth), and corrosive atmospheres. The "1624" suffix denotes ​24V DC operation, ​Ethernet/IP connectivity, and ​16-channel capacity. Certified for ​ATEX/IECEx Zone 1/21​ (Ex d IIC T4 Gb), it incorporates ​auto-calibration, ​sensor drift compensation, and ​​≤5s response time. Integrated ​HART 7.5 communication​ enables remote diagnostics while ​dual-redundant processors​ achieve ​PFHD 1×10⁻⁸/h​ safety integrity. Designed for oil/gas facilities, chemical plants, and wastewater treatment, this module provides early warning for H₂S, CO, CH₄, O₂ deficiency, and VOC hazards with ​predictive fault analytics​ and ​automatic sensor validation.

​2. Critical Technical Specifications​

This module delivers ​16 universal sensor channels​ supporting ​4-20mA, ​RS-485, and ​digital sensor inputs. Key parameters include ​​<0.5µA input noise, ​​±0.1% FS linearity, and ​​≤1s alarm response. Electrical specifications: ​18-30V DC ±10% power​ with ​reverse polarity protection, ​​≤10W consumption, and ​4kV surge immunity. Communication features ​Ethernet/IP CIP, ​Modbus TCP, and ​OPC UA​ protocols. Environmental resilience includes ​​-40°C to +75°C operation, ​15g shock resistance​ (IEC 60068-2-27), ​5g vibration immunity​ (10-150Hz), and ​500hr salt spray resistance​ (ISO 9227). Safety certifications: ​SIL 2 (IEC 61508)​, ​ATEX/IECEx Zone 1/21, ​UL 61010-1, and ​DNV GL. Dimensions: ​120×150×85mm​ (H×W×D) with ​600,000h MTBF​ at 60°C. Sensor compatibility includes ​Honeywell XNX, ​Series 7000, and ​Third-party transmitters​ via universal inputs.

​3. Industrial Safety Applications​

This module excels in critical gas monitoring scenarios:

• ​Oil & Gas Platforms: H₂S detection in drilling areas
• ​Refineries: LEL monitoring at storage tanks
• ​Chemical Plants: Chlorine leak detection in processing units
• ​Wastewater Treatment: Methane buildup in digesters
• ​Pharmaceutical: Solvent VOC monitoring in API synthesis
• ​Power Generation: CO detection in turbine halls
• ​Mining Operations: Oxygen deficiency in confined spaces
• ​Pulp & Paper: ClO₂ monitoring in bleaching plants
  Its multi-gas capability consolidates monitoring for up to 16 zones into a single module, reducing installation costs by 60% compared to discrete detectors. SIL 2 certification enables deployment in safety instrumented systems (SIS) where undetected gas leaks could cause fires, explosions, or toxic exposures per IEC 60079 standards. The IP68 rating withstands submersion in flood-prone areas, while ATEX Zone 1 certification ensures reliable operation in hydrogen environments without additional enclosures.
