Overview

DC-PDIL51 is a Honeywell Series C Mark II digital input module for low-voltage 24 VDC signals. It supplies thirty-two DI-24 channels to the Experion control environment.

The model is identified as the Mark II version without open-wire detection. Engineering should not assign open-wire alarming to this module unless it is provided elsewhere in the field design.

Specs

Features

• High-density 32-channel discrete input interface
• Designed for Series C Mark II I/O infrastructure
• Local software configuration in the Experion environment
• Compatible with redundant and non-redundant IOTA arrangements as specified
• Common Series C mounting and cabinet design

Applications

Applied to 24 VDC field status signals such as contacts, limit switches and auxiliary device indications in process automation systems. Verify input sourcing, common reference and field power before commissioning.

Lifecycle

Retain the exact DC-PDIL51 model where the project depends on the Mark II implementation and absence of open-wire detection. Replacement must preserve IOTA selection and the controller I/O-link configuration.
