Honeywell MC-PDIY22 80363972-150 Digital Input Module 24VDC I/O Processor 32 Inputs

Honeywell MC-PDIY22 Part No. 80363972-150 Digital Input 24VDC I/O Processor 32 Inputs

The Honeywell MC-PDIY22 80363972-150 is a rugged 32-point, 24 V DC digital input module engineered for high-speed, high-availability signal acquisition in Honeywell Experion PKS C300 and Safety Manager systems. Each channel accepts dry-contact or solid-state signals across an 18 V to 30 V range, delivering deterministic on/off status updates with <5 ms filter time for critical interlocking, motor feedback, and emergency-shutdown applications.

Designed for hot-swap installation in any Series C I/O rack, the module draws its 5 V logic supply directly from the redundant backplane—no external power wiring required—and provides 1500 V isolation between field and system circuitry to eliminate ground-loop noise. On-board LED indicators give instant per-channel status, while automatic electronic keying prevents incorrect module insertion. The compact, conformal-coated board operates from 0 °C to +60 °C and withstands 5 g vibration, making it ideal for refineries, chemical plants, offshore platforms, and power-generation facilities.

Front-access spring-cage terminals accept 0.2 mm² to 2.5 mm² conductors for fast, vibration-proof field wiring, and optional cable shields can be landed at the integral ground bar to ensure EMC compliance. The MC-PDIY22 is fully compatible with Honeywell’s Universal I/O (UIO) architecture, allowing future reconfiguration without hardware changes, and supports redundant I/O configurations for maximum process availability.

Certified to IEC 61131-2, UL 508, CE, and ABS marine standards, the 80363972-150 part number is globally recognized by system integrators as the standard 32-point 24 V DC input card for modern Honeywell DCS installations. Each unit ships factory-calibrated with a one-year warranty, complete technical documentation, and worldwide support from Honeywell Process Solutions.
