Honeywell 8C-PCNT03 51454238-175 Controller Module

Product Introduction

The Honeywell 8C-PCNT03 (Part Number: 51454238-175) is a next-generation Series C Controller Module, purpose-built for Honeywell’s Experion Process Knowledge System (PKS) and C300 control environments. Designed for high-performance, deterministic process control, this controller module provides the brain of the C300 controller architecture, enabling real-time execution of control strategies, logic processing, data handling, and communication with the system and field devices.

Compared to previous versions such as the 8C-PCNT01 and 8C-PCNT02, the 8C-PCNT03 offers enhanced processing speed, optimized memory management, and improved reliability for mission-critical operations in harsh industrial environments. This controller is ideal for applications requiring high availability, redundancy, and long-term operational stability.

Product Specifications
