Introduction to WOODWARD 8440-2082
8440-2082 Product Overview
The WOODWARD 8440-2082 is an advanced multi-loop digital control module, a flagship product in the brand’s 8440 series designed for complex industrial process control. It integrates configurable PID logic, high-speed data processing, and flexible I/O expansion to deliver precise regulation for temperature, pressure, flow, and speed parameters in power generation, petrochemical, and manufacturing systems. Widely applied in combined heat and power (CHP) plants, natural gas processing facilities, and industrial boiler systems, it coordinates multiple control loops to optimize energy efficiency, such as synchronizing fuel flow with steam pressure in thermal units. Its rugged design features a corrosion-resistant aluminum housing with IP66 protection, adapting to dusty, humid, and high-vibration industrial environments. Fully compatible with WOODWARD 505E governors and ProTech safety systems, it supports Ethernet/IP and Modbus TCP protocols for seamless integration into smart factory DCS platforms, enabling real-time data sharing and remote control.
