Product Description
The Honeywell 8C-PCNT03 is part of the Experion Series 8 C300 controller family and represents an advanced and compact controller solution designed for process control applications within distributed control systems (DCS). This model integrates control execution, communication interfaces, and redundancy capabilities directly within the module, eliminating the need for additional interface cards or communication units.
Engineered with Honeywell’s deterministic Control Execution Environment (CEE), the C300 controller ensures high-performance control processing, robust communication across networks, and seamless integration with Series 8 I/O modules. It supports peer-to-peer communication and high availability features essential for critical infrastructure in industries such as oil and gas, refining, chemicals, and power generation.
