Product Overview

The Honeywell CC-PCNT02 (Part Number: 51454551-275) is a high-performance C300 Controller for the Experion PKS Series C system. It executes complex control strategies, manages extensive I/O communications, and facilitates peer-to-peer data exchange across the control network. This module delivers deterministic performance required for high-speed process control loops.

The -275 revision features advanced processing capabilities to handle demanding computational tasks without sacrificing system stability. Its vertical Series C form factor ensures natural convection cooling for heavy processing loads.

Technical Data

Operational Excellence and Reliability

• Deterministic Execution: Ensures control blocks execute at precise intervals for stability in sensitive processes.

• G3 Conformal Coating: Provides corrosion resistance in harsh environments with high humidity or sulfur.

• Native Redundancy: Pairs two modules for seamless "bump-less" switchover in case of hardware failure.

• Future-Proof Design: Scalable memory and processing power allow firmware upgrades for new Experion features.

Typical Applications

• Refinery Central Control: Managing thousands of I/O points across multiple distillation units with sub-second response.

• Liquefied Natural Gas (LNG): Controlling complex cryogenic processes requiring precise temperature and pressure.

• Large Power Plants: Coordinating boiler-turbine operations and balancing electrical loads in real-time.

• Continuous Chemical Processing: Executing advanced batch recipes with high-precision timing and data logging for compliance.

FAQ

Q1: What is the difference between the CC-PCNT01 and the CC-PCNT02?
A1: The CC-PCNT02 (51454551-275) offers enhanced memory and processing speed compared to the PCNT01. The -275 revision also provides better hardware protection against corrosive atmospheres.

Q2: Does the CC-PCNT02 require a specific battery for memory backup?
A2: Yes, the C300 uses a RAM-based memory system that requires a battery module (located on the IOTA) to preserve the control strategy during power outages.

Q3: How do I address a "Redundancy Lost" alarm on this module?
A3: Check the status LEDs on both modules. This alarm usually indicates a synchronization issue or a failure in the redundancy cable connecting the controller IOTAs.

Q4: Can I use this controller with older Series A or Series M I/O?
A4: While designed for Series C I/O, the C300 can communicate with legacy I/O via specific interface modules or over the network using FTE.
