Honeywell FC-SAI-1620M Safety Manager 16-Channel Analog Input Module

Product Overview

The FC-SAI-1620M (Model: FC-SAI-1620M) is a high-density safety analog input module specifically engineered for the Honeywell Safety Manager® and Experion® PKS Safety Instrumented System (SIS). This module provides 16 independent analog input channels, organized into two groups of eight, to facilitate high-fidelity acquisition of field signals from transmitters and sensors.

Designed for SIL3 safety-critical applications, the FC-SAI-1620M (Part Number: FC-SAI-1620M) handles standard 4–20 mA current loops, typically converted to a 0–4 V range via a field termination assembly. It is certified for Class I, Division 2 hazardous locations, ensuring stable performance in demanding petrochemical, oil and gas, and power generation environments. With integrated galvanic isolation and advanced self-diagnostics, the module ensures maximum safety integrity and minimal downtime for industrial automation ecosystems.
