Introduction to WOODWARD 8237-1597
8237-1597 Product Overview
The WOODWARD 8237-1597 is a high-precision digital signal regulator, a key member of the brand’s 8237 series tailored for industrial process control and turbine auxiliary systems. It specializes in converting and conditioning analog control signals, integrating linearization algorithms and anti-interference technology to ensure stable output for critical control loops. Widely applied in power generation, petrochemical, and marine engineering, it processes speed feedback signals for steam turbine lubrication systems, converts pressure signals for oil pipeline compressors, and stabilizes control signals for gas turbine fuel supply modules. Its compact and rugged design features a dust-proof metal housing with industrial-grade EMI shielding, adapting to high-vibration and high-temperature environments in power plant control rooms and offshore platforms. Fully compatible with WOODWARD 505 series controllers and 2301A governors, it supports standard Modbus protocol for seamless integration into DCS systems, enabling real-time signal monitoring and remote parameter adjustment to enhance control loop reliability.
