Description
The Woodward Peak200 (specifically catalog number 8200-1501) is a microprocessor-based digital controller designed for the operation, regulation, and protection of small single-valve or single valve-rack industrial steam turbines and turboexpanders.
The “HV” suffix and code designations identify it as a High-Voltage (HV) power variant of the Peak200 platform, engineered to drive final control elements (such as steam inlet valves via hydraulic or electric actuators) while managing critical speed, load, and auxiliary process loops.

Core Features & Operating Capabilities
- Integrated Dual-PID Control: Features both a primary speed/load PID and a secondary configurable “Cascade” PID. This allows smooth, bumpless transfer between controlling turbine speed/power and managing external plant parameters (such as inlet/exhaust header pressure or pump/compressor flow).
- Built-In Overspeed Protection: Equipped with dedicated overspeed sensing and trip algorithms, complying with API 611 requirements to safely shut down the turbine during runaway conditions.
- First-Out Indicator & Event Logging: Automatically captures and timestamps shutdown logs, alarm events, and first-out fault conditions, drastically simplifying on-site troubleshooting.
- Internal Turbine Simulator: Includes built-in simulation logic, enabling engineers to test control loops, configuration settings, and responses prior to live commissioning.
- Rugged Environmental Build: Built with conformal coating options to resist corrosive gases (H2S, SO2, NO2) and certified for hazardous locations (such as ATEX Zone 2 / Class I, Div 2 areas).
