Woodward|8237-1599|ProTech-GII Overspeed Protection Device
Description
The 8237-1599 is a panel-mount ProTech-GII overspeed protection device designed for steam, gas, and hydro turbines. It monitors turbine rotor speed and acceleration, issuing shutdown commands to the turbine's trip valve(s) upon detecting overspeed or over-acceleration events. This model supports high voltage (HV) inputs with voted relay outputs.
Features
- Triple Modular Redundancy: Ensures no single-point failure affects system reliability.
- Voted Inputs and Relays: Uses 2-out-of-3 voting logic for critical decisions.
- Modbus Communication: Facilitates data exchange and configuration.
- Automated Testing: Includes predefined test routines for system verification.
- Alarm and Trip Logs: Time-stamped logs for event tracking and analysis.
Technical Specifications
- Mounting: Panel mount
- Voltage Inputs: High voltage (HV/HV)
- Relay Outputs: Voted relays (3 total)
- Speed Range: 0.5 to 32,000 rpm
- Response Time: Up to 826 milliseconds (depending on configuration)
- Inputs per Module: One speed input (MPU or PROX), three modules total
- Additional Outputs: One alarm relay output and one analog speed output per module
- Compliance Standards: API-670, API-612, API-611, IEC61508 (SIL-3)
- Communication: Modbus interface
- Environmental Resistance: Suitable for Class 3C2 environments, sulfur-resistant conformal coating against H2S and SO2 gases
