Honeywell MC-GOAX02 Analog Output Module

Product Overview

The Honeywell MC-GOAX02 generates precise analog output signals for process control applications. This module provides four isolated output channels with 4–20 mA current loop capability. It converts digital commands from the controller into proportional analog values for field devices. The unit integrates seamlessly into Honeywell Series C I/O chassis.

Technical Specifications

Physical Dimensions and Mounting

This module measures 125 mm in height, 45 mm in width, and 160 mm in depth. The unit weighs approximately 0.38 kg. It mounts directly onto a standard DIN rail inside the Series C cabinet. The front panel includes four LED indicators for per-channel output status. These LEDs provide immediate visual confirmation of signal generation activity.

Electrical Interface and Connectivity

A 37-pin D-sub connector serves as the primary interface for field wiring connections. Each output channel provides a two-wire termination for current loop devices. The module also includes an internal 24 VDC loop power supply for each channel. This feature eliminates the need for external power sources for most actuators. The analog outputs operate in sourcing mode only for standard compatibility. Field devices like I/P transducers, valve positioners, and chart recorders connect directly to these terminals.

Performance and Signal Integrity

The MC-GOAX02 delivers a 12-bit resolution output with exceptional linearity across the full range. The module updates all four channels simultaneously for coordinated control response. Built-in diagnostics monitor each output for open-loop or short-circuit conditions. The module reports any signal anomalies to the main controller immediately. Furthermore, the output circuitry includes ESD protection for robust industrial operation. The loop resistance capability reaches up to 750 Ω at 24 VDC.

Installation and System Integration

This output module integrates with Honeywell TDC 3000 and Experion PKS control platforms. You can place the module in any available I/O slot without special configuration. The backplane handles all address assignment and power distribution automatically. Always verify that the loop wiring polarity matches the termination diagram. For critical control loops, consider using redundant modules for fail-safe operation.

Environmental Compliance

This module carries CE marking and UL certification for industrial applications. It also complies with RoHS and WEEE environmental directives for sustainable manufacturing. The conformal coating protects the PCB against moisture and dust ingress. This coating enhances long-term reliability in harsh plant conditions.
