Product Details
Product Description
The MC-GOAX02 (51304638-175) is a high-performance Galvanically Isolated Analog Output Field Termination Assembly (FTA) specifically engineered for Honeywell Experion PKS and legacy TDC 3000 Distributed Control Systems. This 16-channel interface provides a critical safety and signal conditioning barrier between the system's Analog Output (AO) processors and field-side actuators or valves. By utilizing galvanic isolation, the MC-GOAX02 effectively eliminates ground loops and protects sensitive controller circuitry from high-voltage transients and electromagnetic interference (EMI). The "MC" designation confirms that the assembly is conformal coated, ensuring long-term reliability in corrosive or humid industrial environments.

Signal Integrity and Field Safety
The MC-GOAX02 (51304638-175) is an essential component for facilities that prioritize process uptime and hardware protection, such as refineries, offshore platforms, and chemical plants. Its galvanic isolation barrier ensures that an electrical fault at a specific valve or actuator does not propagate back to the central processor or affect adjacent channels. Furthermore, its support for redundant I/O processors ensures that the 4–20 mA control signal remains stable and active even during a primary hardware failover or I/O Link cable maintenance.
Frequently Asked Questions
-
What is the primary benefit of the MC-GOAX02 over non-isolated FTAs?
The MC-GOAX02 provides a physical isolation barrier for every channel. This prevents ground loop noise from distorting output signals and ensures that field-side surges do not damage the expensive I/O modules in the control rack.
-
Is this module suitable for use in corrosive environments?
Yes. The MC-GOAX02 (51304638-175) is manufactured with a conformal coating on the PCB, providing high-level resistance to salt spray, humidity, and chemical vapors typical in industrial settings.
