Description
Product Overview
The Woodward 8200-1312 is a high-performance digital servo controller designed for precision motion control in critical industrial applications. As part of Woodward’s 8000 series of advanced motion solutions, this ruggedized module provides closed-loop positioning for hydraulic and pneumatic actuators with ±0.025% repeatability. The 8200-1312 features dual-core 64-bit processing with nanosecond-resolution timing, enabling ultra-precise control of valves, dampers, and other final control elements in power generation, oil & gas, and heavy industrial processes. Its all-metal IP69K-rated enclosure withstands extreme environments (-40°C to +90°C operating temperature, 10G vibration, 50G shock), making it ideal for offshore platforms, naval vessels, and other demanding installations. With embedded AI-based predictive maintenance and cyber-secure TSN Ethernet connectivity, the Woodward 8200-1312 represents the cutting edge of industrial motion control technology.

WOODWARD 8200-1312
Main Features and Advantages
AI-optimized control: The Woodward 8200-1312 implements machine learning-based model predictive control (MPC) that continuously adapts to changing system dynamics, reducing settling time by 60% compared to conventional PID. Its NeuralFriction™ compensation automatically characterizes and cancels nonlinear stiction effects.
Deterministic networking: With IEEE 802.1CB frame replication and TSN time-aware shaping, the controller guarantees ≤10µs cycle times for synchronized multi-axis applications. The dual-redundant 10Gbps Ethernet ports support zero-latency failover during network disruptions.
Military-grade reliability: Featuring triple-redundant FPGAs with lockstep processing, the 8200-1312 meets MIL-STD-810H specifications for shock/vibration. Its hermetically sealed connectors and conformal-coated triple-PCB stack survive salt fog, hydrocarbons, and high-pressure washdowns.
Predictive health monitoring: Embedded vibration spectrum analysis (0-25kHz bandwidth) detects mechanical wear patterns, while coil impedance monitoring predicts actuator winding degradation. The controller generates ISO 13374-3 compliant health reports with remaining useful life estimates.
