Honeywell MC-PAOY22 Coated Analog Output Module 80363969-150

Product Overview

The Honeywell MC-PAOY22 (Part Number 80363969-150) operates as a high-integrity Analog Output Processor designed for the Honeywell Experion PKS and TDC series. This module manages 16 independent, isolated channels to drive field-side control valves, actuators, and variable speed drives. We supply this unit as 100% brand new and original, featuring the "Coated" hardware specification for superior resistance to corrosive industrial atmospheres. The MC-PAOY22 converts 12-bit digital commands into precise analog current or voltage signals, ensuring stable and repeatable process control in safety-critical refinery, petrochemical, and power generation environments.

Technical Specifications

The MC-PAOY22 integrates high-resolution signal generation with industrial-grade hardening:

Engineering Advantages

• Superior Accuracy for Critical Loops: The module delivers a governing accuracy of ±0.1% of the full scale. This precision ensures that control valves respond exactly to the controller's logic, reducing process oscillation and improving final product consistency.

• ISA G3 Conformal Coating: The 80363969-150 revision features specialized coating to withstand corrosive gases such as $H_{2}S$ and $Cl_{2}$. This protection prevents "silver whisker" growth and circuit corrosion, which are common causes of failure in pulp and paper or wastewater treatment facilities.

• High-Density Signal Isolation: Galvanic isolation between channels prevents ground loop interference and protects the internal system logic from field-side electrical surges. A fault on one actuator line will not disrupt the remaining 15 outputs.

• Extended Drive Capability: Supporting loads up to 750 Ω, the MC-PAOY22 drives analog signals over long cable runs without requiring external signal boosters, simplifying field wiring in large-scale plant layouts.

FAQs

• What is the difference between the MC-PAOY22 and the MU-PAOY22?

  The MC-series typically denotes "Coated" versions or specific processor-level hardware intended for the High-Performance Process Manager (HPM) or Experion platforms, whereas MU-series often refers to standard termination or I/O units. The 80363969-150 is the specific coated processor for 16-channel AO applications.

• Can I configure specific channels for voltage and others for current?

  Yes. The module supports flexible configuration. You define whether a channel operates as a current loop (4-20mA) or a voltage signal (0-10V) through the Honeywell control system software.

• Is this module suitable for outdoor control cabinets?

  With an operating temperature range of -40 °C to +70 °C and its G3 coating, the MC-PAOY22 thrives in harsh environments. However, ensure your cabinet maintains a non-condensing atmosphere (5-95% RH) to maximize the module's lifespan.
