Description
Product Overview
The Woodward 8200-1302 is a high-reliability digital actuator controller designed for precision positioning of hydraulic and pneumatic actuators in critical industrial applications. As part of Woodward’s 8000 series of motion control solutions, this advanced module provides closed-loop control for valves, dampers, and other final control elements in power generation, oil & gas, and heavy industrial processes. The 8200-1302 combines 32-bit floating-point processing with Woodward’s proven control algorithms to deliver ±0.05% positioning accuracy in demanding operating conditions. Its ruggedized design features stainless steel housing (IP67 protection) and MIL-SPEC connectors, ensuring reliable operation in environments with extreme temperatures (-40°C to +85°C), vibration (up to 5G), and electrical noise. The controller supports multiple feedback types including LVDT, RVDT, and potentiometer signals, with dual-channel redundancy for mission-critical applications. Integrated predictive maintenance algorithms monitor actuator performance trends to prevent unplanned downtime.
