Product Overview
The Woodward 8237-1600 is a high-performance ProTech-GII series overspeed safety device designed to safeguard steam, gas, and hydro turbines across industrial applications. As a critical component in turbine control systems, this module continuously monitors rotational speed and acceleration, triggering immediate shutdowns to prevent catastrophic failures. Its triple-redundant architecture and advanced diagnostic capabilities make it a cornerstone for ensuring operational reliability in power generation, oil and gas, and manufacturing sectors.
Integrated with MPU (Magnetic Pickup Unit) detection, the Woodward 8237-1600 verifies sensor connectivity and functionality before and during turbine operation. This proactive approach minimizes false trips and ensures accurate speed measurement. The device supports both high-voltage (115/220 VAC) and low-voltage (24 VDC) power inputs, offering flexibility for diverse system configurations. Its Modbus communication interface enables seamless integration with higher-level control systems, facilitating real-time monitoring and data logging.
Part of Woodward’s ProTech-GII platform, the 8237-1600 is engineered to withstand harsh environments, including sulfur-contaminated atmospheres, through its conformal coating technology. This resilience, combined with an IP56-rated enclosure, ensures long-term performance in industrial settings where reliability is non-negotiable. By combining speed control, acceleration detection, and automatic test routines, the module delivers comprehensive protection while reducing maintenance downtime.

Main Features and Advantages
Dual-Mode Protection
The Woodward 8237-1600 combines speed monitoring and acceleration detection to identify both gradual overspeed and sudden acceleration events. By analyzing the derivative of the speed signal, it can distinguish between normal operational fluctuations and dangerous conditions, ensuring precise trip decisions. This dual-mode approach significantly reduces false alarms while enhancing safety.
Rugged Design for Harsh Environments
With a conformal coating that resists sulfur dioxide (SO₂) and hydrogen sulfide (H₂S) corrosion, the module excels in oil refineries, chemical plants, and other sulfur-rich environments. Its IP56-rated enclosure protects against dust and water ingress, maintaining performance in extreme temperatures and humidity levels up to 95% non-condensing.
Modular Redundancy for Continuous Operation
Featuring a triple-module design, the 8237-1600 allows online maintenance without system shutdowns. Users can replace a faulty module while the other two continue operating, minimizing downtime. The 2-out-of-3 voting logic ensures reliable trip signals, even in the event of a single module failure.
Automated Testing and Diagnostics
The device performs routine overspeed tests using an internal frequency generator, simulating fault conditions to validate functionality. Test results are logged for compliance and maintenance planning. Additionally, real-time diagnostics monitor MPU connectivity and relay health, providing actionable insights to operators.
Flexible Integration
Supporting both high- and low-voltage inputs, the 8237-1600 adapts to existing turbine control systems. Its Modbus interface enables seamless integration with PLCs, SCADA systems, and HMIs, facilitating centralized monitoring and remote parameter adjustment.
Application Areas
Power Generation
In thermal and hydroelectric power plants, the Woodward 8237-1600 safeguards turbines from overspeed during load shedding or grid instability. Its rapid response time (< 50 ms) prevents catastrophic damage to generator shafts and blades, ensuring uninterrupted power supply. For example, in combined-cycle power plants, it coordinates with governor systems to maintain speed control during transitions between gas and steam turbine modes.

Oil and Gas
Offshore platforms and refineries rely on the 8237-1600 to protect gas turbines driving compressors and pumps. Its sulfur-resistant design is critical in sour gas environments, where corrosion can compromise sensor accuracy. The module’s redundancy ensures continuous operation during scheduled maintenance or unplanned outages.
Industrial Manufacturing
In steel mills and paper plants, the 8237-1600 monitors steam turbines powering large machinery. By preventing overspeed caused by process upsets, it reduces downtime and extends equipment lifespan. For instance, in a paper mill, it ensures stable operation of turbine-driven paper machines, maintaining product quality and production efficiency.
Water and Wastewater Treatment
In hydroelectric facilities and water pumping stations, the module protects hydro turbines from overspeed during sudden changes in water flow. Its IP56 rating makes it suitable for outdoor installations exposed to moisture and debris.
