Woodward 8237-1369 Digital Controller  

Woodward 8237-1369 is a ProTech GII series turbine overspeed protection controller responsible for speed monitoring and protection interlocking in power plant units.
Characteristics
1. Adopting a two out of three voting architecture, even if a single board is abnormal, the protection logic will not malfunction
2. It comes with a continuous self check function, which can check the speed probe and internal circuit faults in real time
3. Support multiple overspeed thresholds, and can set pre alarm and emergency trip values in advance
4. The module supports hot swapping, and maintenance and replacement do not require stopping the entire unit for protection
5. With event records, the jump alarm information will be saved for easy troubleshooting afterwards

parameter
1. Adapt MPU magneto electric speed sensor to collect speed signals
2.8 relay outputs, used to trigger alarms and shutdown interlocks
3. Modbus RTU communication, can be connected to DCS backend to view data
4. The board is coated with a three proof layer, which can resist on-site sulfide corrosion
5. Panel installation structure, with control cabinet openings directly embedded
Application
1. Overspeed protection for gas turbines and steam turbines
2. Safety monitoring of rotating equipment for generator sets
3. Chemical power workshop turbine protection system
4. Replacement of ProTech GII equipment spare parts in the power plant
5. High safety level rotating machinery interlocking project
Woodward 8237-1369 is a core component of unit safety protection, and there is a high demand for maintenance and replacement in power plants.
