Honeywell CC-PDIH01 Experion Series C High Voltage Digital Input Module

Description

The Honeywell CC-PDIH01 is a 32-channel high voltage digital input module engineered specifically for the Experion Series C distributed control system (DCS). This module interfaces high-voltage discrete signals directly with the control architecture, accommodating inputs ranging from 120VAC, 125VDC, to 250VAC. It provides localized signal processing, optical galvanic isolation between the field inputs and the system logic, and internal diagnostics to ensure continuous data integrity in critical process automation environments.

Designed for rack-mounted installation within Series C I/O carriers, the CC-PDIH01 supports redundant module configurations to eliminate single points of failure in high-availability loops. The unit handles direct and reverse input logic configurations through software settings, minimizing the need for external hardware adjustments and streamlining panel wiring architecture.

Features

• 32 discrete input channels supporting high-voltage ranges (120VAC, 125VDC, and 250VAC)
• Galvanic optical isolation between field circuits and internal system logic
• Full support for redundant module pairs to maintain uninterrupted operation
