Honeywell FC-GMLA16 Analog Input Module 4-20mA 16-Channel

Product Overview

The FC-GMLA16 (Model: FC-GMLA16) is a high-density, safety-rated analog input module engineered by Honeywell for the Safety Manager® and Experion® PKS architectures. This module serves as a critical interface for Safety Instrumented Systems (SIS), designed to convert 16 independent 4–20 mA current loop signals from field transmitters into precise digital data for safety logic processing.

Built for high-consequence industrial environments, the FC-GMLA16 (Part Number: FC-GMLA16) incorporates advanced signal conditioning, including per-channel fault detection for open and short circuits. It is frequently paired with MTL Field Termination Assemblies (FTAs) to provide galvanic isolation and signal integrity in petrochemical, power generation, and hazardous processing sectors. The module's robust design ensures deterministic performance and compliance with stringent safety standards for process monitoring and emergency shutdown (ESD) applications.
