Product Overview

The Honeywell MC-PDOY22 (Part Number 80363975-150) is a high-density discrete interface module engineered for the Experion® Series C I/O environment. This module provides 32 independent digital output channels, allowing a single slot in the DCS rack to manage a wide array of field-level binary devices. Designed for precision and reliability, the MC-PDOY22 utilizes Form C dry contact relay outputs, making it highly adaptable for switching various signal types without requiring complex interposing hardware for low-power applications.

As a core component of the Series C architecture, this module is built to provide maximum signal density in a compact footprint. It effectively bridges the gap between the C300 controller logic and physical equipment such as solenoids, indicators, and motor starters. Its design emphasizes electrical safety and system integrity, ensuring that high-voltage transients on the field side do not migrate to the sensitive control network.
