Honeywell DC-PDOD51 Digital Output Module

Product Description

The Honeywell DC‑PDOD51 is a 16-channel digital output (DO) module designed for integration with Honeywell Experion PKS and C300 control platforms. Part of Honeywell’s robust Series 8 I/O family, this module provides isolated 24 VDC outputs to drive field devices such as solenoids, relays, contactors, and indicator lights. Its design emphasizes reliability, online maintainability, and suitability for continuous operation in demanding industrial environments.

Key Features

• 16 individually isolated 24 VDC digital outputs

• Sourcing outputs capable of handling up to 0.5 A per channel (load-dependent)

• Channel-to-channel and field-to-system galvanic isolation

• Comprehensive protection: short-circuit, over-current, thermal shutdown, and reverse-polarity protection

• Per-channel diagnostics for open-circuit and short-circuit conditions

• Hot-swappable within Series 8 I/O chassis for uninterrupted operation

• Supports redundant configurations for enhanced reliability

• Status and health indicators via module LEDs
