Product Description

Overview

The Honeywell CC-PDIS01 is a high-precision Digital Input Sequence of Events (DISOE) module designed for integration with the Experion PKS Series C I/O system. It provides fast, time-stamped capture of 24V DC discrete signals from field devices, enabling accurate post-event diagnostics in critical industrial applications.

This module is ideal for environments where millisecond-level event sequencing is essential, including power generation, chemical processing, and oil and gas emergency shutdown systems.

Product Description

The CC-PDIS01 interfaces directly with 24V DC discrete field signals and communicates with the C300 controller via an I/O Termination Assembly (IOTA). Its main function is to capture the precise timing of digital events, providing critical Sequence of Events (SOE) data for control, monitoring, and safety analysis.

Key Functionalities:

• High-resolution SOE recording: Millisecond-accurate timestamps for event sequencing.

• Redundant-ready design: Supports optional redundancy with compatible IOTA modules (CC-TDIL11).

• On-board excitation: Supplies 24V DC to field contacts directly, reducing cabling complexity.

• Diagnostic features: Detects open or broken wires to maintain data integrity.
