Series 8 C300 Controller – Product Overview
The Honeywell 8C-PCNT02 is part of the Series 8 C300 Controller family, designed to deliver robust and deterministic control in distributed control systems (DCS). It leverages the field-proven Control Execution Environment (CEE) to execute advanced control strategies, supports modular I/O connections, and offers high availability through optional redundancy.
The controller integrates seamlessly with Experion Process Knowledge Systems (PKS), enabling flexible, scalable control solutions with minimal footprint. It mounts directly onto a Series 8 I/O Termination Assembly (IOTA), offering simplified field wiring, reduced installation costs, and enhanced maintenance efficiency.
