Honeywell MC-GOAX02 51304638-175 Analog Output Isolator

Honeywell MC-GOAX02 51304638-175 Analog Output Galvanic Isolator Assembly

Product Description

The MC-GOAX02 (51304638-175) is a precision Analog Output (AO) Galvanic Isolator Assembly belonging to Honeywell’s Series MC I/O family. This module is specifically engineered for Honeywell Experion PKS, FSC (Fail Safe Control), and TPS/TDC 3000 systems. It provides a secure electrical barrier between the control logic and field devices, effectively eliminating ground loops and protecting sensitive system electronics from hazardous electrical transients.

Equipped with two independent channels, the MC-GOAX02 (51304638-175) acquires signals from the controller and converts them into isolated 4–20 mA or 0–10 V DC outputs to drive field actuators and control valves. Its microprocessor-based design ensures high-fidelity signal transmission with a typical accuracy of ±0.1%, making it ideal for low-density, mission-critical applications in functional safety environments.
