The Honeywell FS-TSGAS-1624 is a 16-channel Fail-Safe Gas and Flame Detector Input Field Termination Assembly (FTA) designed for integration with Honeywell Safety Manager safety instrumented systems. This module serves as a critical interface between field-mounted gas detectors, flame detectors, and the SAI-1620m safe analog input module, ensuring reliable signal acquisition for safety-critical applications.

Features

• 16-channel analog input interface for gas and flame detectors.
• Supports standard 0–20 mA and 4–20 mA input signals.
• Provides linear conversion of field signals to levels required by the SAI-1620m module.
• Integrated per-channel 500 mAT fuse for transmitter power protection.
• Supports HART communication for advanced diagnostic and configuration capabilities.
• Universal snap-in mounting for standard DIN EN rails.

Applications

• Emergency Shutdown Systems (ESD): Triggers facility shutdown upon detection of hazardous gas or flame conditions.
• Fire and Gas (F&G) Systems: Provides a robust input interface for combustible/toxic gas and flame monitoring sensors.
• Critical Process Protection: Processes 0-20 mA safety signals within the Honeywell Safety Manager architecture.
• Turbomachinery: Supports control and protection loops for large-scale turbines and compressors.
• Pipeline Infrastructure: Facilitates leak monitoring across extensive industrial pipeline networks.

Technical Specifications

Installation Guidelines

• Mount the FTA securely on standard DIN EN rails (TS32 or TS35 x 7.5).
• Ensure a minimum rail length of 226 mm to accommodate the module footprint.
• Use the dedicated terminal on each channel for field cable shield termination to minimize EMI.
• Verify power supply polarity and connections before energizing the system.
• Always power down the system before inserting or removing the module to prevent electrical damage.
• Ensure adequate ventilation in the cabinet to maintain operating temperature limits.

FAQ

What is the primary function of the FS-TSGAS-1624?

It acts as a 16-channel interface that converts 0(4)-20 mA analog field signals from gas and flame detectors into the signal levels required by the SAI-1620m high-density analog input module.

Is this module compatible with HART communication?

Yes, the module supports HART communication, allowing for advanced device diagnostics and configuration of connected field instruments.

How are the field transmitters protected?

Each analog input channel is equipped with an individual 500 mAT fuse to protect the power supply to the field transmitter.
