Honeywell FC-TSGAS-1624 Safe Gas/Flame Detector Input FTA

TSGAS-1624 Safe Gas/Flame Detector Input FTA (0-20 mA, 16 Channels)

The TSGAS-1624 module serves as the interface between gas/flame detectors in the field and the safe high-density analog input module SAI-1620m in Safety Manager. It features sixteen analog input channels suitable for both safety-related and non-safety-related applications. This module utilizes a SICC-0001/Lx system interconnection cable to transfer the 16 input signals to a redundant pair of SAI-1620m modules.

Main Functions:

• Signal Conversion: Linear direct conversion of 0(4)-20 mA DC field signals to the signal levels of the safe high-density analog input module SAI-1620m.
• Power Distribution: Provides power supply distribution to each transmitter with 500 mA fused protection.
• Monitoring: Enables monitoring of the external power connected to the TSGAS-1624 module.
