FS-TSGAS-1624 Fail-Safe Gas-Flame Detector Input Field Termination Assembly | Honeywell

The Honeywell FS-TSGAS-1624 is a 16-channel fail-safe gas-flame detector input field termination assembly (FTA). It functions as a dedicated signal conditioning interface, receiving analog transmitter signals from field-mounted gas and flame detectors and converting them for safety system processing modules.

Analog Signal Processing and Output Conditioning

The assembly supports 16 analog input channels rated for 0-20 mA current loops with a common 0 V reference. Featuring an internal input resistance of 500 Ω ±5%, the assembly conditions incoming field currents into a proportional 0-4 VDC voltage output signal directed to the connected SAI-1620m safety analog input module, maintaining high signal precision with 0.1% accuracy.

Power Requirements

The module operates from an external 24 VDC power supply. Without accounting for field load currents, the internal circuitry of the assembly draws a baseline current of 3 mA during standard operation.

Frequently Asked Questions

Q: Which input module does the FS-TSGAS-1624 interface with?

A: The assembly conditions 0-20 mA field signals into a 0-4 VDC output specifically designed for connection to the Honeywell SAI-1620m module.

Q: What power source is required to operate the FS-TSGAS-1624?

A: It requires an external 24 VDC power supply, drawing a base current of 3 mA excluding connected field device loads.
