Honeywell 80363975-150
Product Name: MC-PDOY22 Digital Output Processor (32-Channel)
Introduction: The 80363975-150 is a 32-channel digital output processor module for Honeywell distributed control systems. It provides reliable isolated output switching for relays, solenoids, and industrial field devices, and supports redundant system configurations for high-availability process control.

Features: High-density 32-point discrete output in a single slot. Optically isolated outputs improve signal integrity and protect against field-side faults. Compatible with isolated 24 VDC, solid-state, and electromechanical relay FTAs. Supports relay outputs up to 240 VAC / 125 VDC. Output readback diagnostics enable internal fault verification. Hot-swap capable on compatible I/O Link architectures.
Applications: Complex process control in TDC 3000 HPM and Experion PKS C300 systems; driving relays, solenoids, lamps, and other industrial output devices in oil & gas, chemical, and power generation facilities. Enables phased migration from TDC 3000 to Experion PKS by operating under either controller architecture.
Working Principle: The controller writes discrete output commands over the I/O Link. The MC-PDOY22’s open-collector transistor drivers sink current to ground to activate the connected load. Optical isolation separates the logic side from the field side. Depending on the FTA, outputs can be configured as solid-state 24 VDC, or as Form-C relay contacts rated for AC/DC loads.
Installation Requirements: Install in a standard HPM or C300 I/O rack slot. Select the appropriate FTA: OY22/OY62 for 24 VDC solid-state outputs; OY23/OY63 for relay outputs (two FTAs required for all 32 relay outputs). Ensure the 24 VDC backplane supply is present. Verify output states via the engineering station after commissioning.
Precautions: Verify the correct FTA type before wiring—relay FTAs require two units to access all 32 points. Do not exceed 250 VAC / 125 VDC on relay outputs. Observe polarity on solid-state outputs. The conformal coating protects against moisture and dust but does not permit outdoor exposure without a suitable enclosure.
