FC-TSAI-1620M | Honeywell | Analog Input Termination

Product Overview

The FC-TSAI-1620M (Part Number: FC-TSAI-1620M) is a Honeywell Field Termination Assembly engineered for use with the SAI-1620M safe analog input module within Safety Manager and Experion PKS systems. As part of Honeywell’s C-Series I/O portfolio, this module provides a reliable interface between field-mounted analog transmitters and safety control hardware.

Designed for high-integrity safety applications, the unit supports up to 16 analog current input channels and ensures stable signal conditioning in electrically noisy and hazardous environments. Its architecture is optimized for process industries where measurement accuracy, system availability, and regulatory compliance are critical.

Functional Capabilities and Applications

The FC-TSAI-1620M (FC-TSAI-1620M) enables secure termination and conditioning of 0–20 mA and 4–20 mA signals from field devices such as pressure, temperature, flow, and level transmitters. Channels are arranged into two independent groups with a shared reference, simplifying wiring while maintaining signal integrity.

This Field Termination Assembly is widely deployed in Safety Instrumented Systems (SIS) across oil & gas production, refining, chemical processing, petrochemical facilities, and power generation plants. Its certification for Class I, Division 2 locations makes it suitable for installation close to field equipment in hazardous areas.

Design and Engineering Characteristics

Built for continuous industrial operation, the module incorporates precision resistors, integrated fusing, and protective circuitry to safeguard both field devices and control electronics. The DIN-rail form factor allows efficient panel layout and straightforward maintenance access.

When paired with the SAI-1620M input module, the FTA converts loop current signals into voltage levels required by the C-Series I/O system while maintaining high measurement accuracy and diagnostic transparency.
