Function and Working Principle
The IS200VTURH1B operates as the core protection controller in the turbine system.
Its main functions include:
- Monitoring turbine speed using MPU (magnetic pickup) signals
- Detecting overspeed conditions and initiating emergency trips
- Controlling primary trip relays connected to turbine shutdown circuits
- Monitoring shaft current and voltage for abnormal conditions
- Supervising flame detection inputs in gas turbine applications
- Executing safety logic independent of normal control functions
When unsafe conditions are detected, the board triggers automatic turbine shutdown (trip) to protect equipment and personnel.
