Honeywell FC-TSAI-1620M 16-Channel Analog Input FTA
The FC-TSAI-1620M functions as a high-integrity Field Termination Assembly designed for Honeywell Safety Manager platforms. This module provides 16 channels of precise analog signal conditioning, acting as the critical physical interface between field transmitters and the safety controller.
Signal Conditioning & Conversion
The unit processes input signals ranging from 0 to 25 mA, supporting standard 4-20 mA loops with a built-in 250 ohm input resistance. It converts these field signals into a 0 to 4 VDC output for the safety module while maintaining an accuracy of 0.1%.
Circuit Protection & Power Distribution
Each channel features an individual 315 mAT slow-acting fuse sized 5 x 20 mm to isolate field wiring faults and protect neighboring channels. The assembly provides up to 120 mA of external 30 VDC power to support passive transmitters, eliminating the need for separate loop power distribution hardware.

Frequently Asked Questions
Q: How does the FC-TSAI-1620M handle passive field transmitters? A: The FTA includes circuitry that supplies up to 120 mA to passive transmitters, removing the requirement for external power rails for 2-wire loops.
Q: What maintenance is required for the input fuses? A: The module utilizes standard 315 mAT slow-acting 5 x 20 mm fuses that can be accessed and replaced on the assembly without removing the entire unit from the DIN rail.
