Honeywell FC-TSHART-1620M | 16-Channel HART Analog Input

Product Overview

The Honeywell FC-TSHART-1620M functions as a 16-channel HART-enabled Field Termination Assembly for the Safety Manager system. This module interfaces directly with HART smart transmitters and sensors, converting 4-20 mA analog signals for the SAI-1620M high-density input module . Moreover, the FC-TSHART-1620M enables simultaneous analog measurement and digital HART communication over the same two wires.

Technical Specifications

The FC-TSHART-1620M organizes its 16 input channels into two groups of eight, each sharing a common 0V reference . This module provides a 250Ω input resistance with ±1% tolerance and accepts a 0-25 mA DC input range, with 4-20 mA as the typical operating signal . For output, the unit delivers 0-4 V DC to the SAI-1620m module with 0.10% accuracy . Furthermore, the module’s linear conversion ensures precise signal integrity for safety-critical applications.
