Function and Working Principle
The IS200VTURH2B operates as a core safety protection controller in turbine systems.
Its key functions include:
- Monitoring turbine speed via magnetic pickup (MPU) sensors
- Detecting overspeed and abnormal acceleration conditions
- Initiating turbine trip signals for emergency shutdown
- Coordinating safety interlocks with other protection modules
- Processing flame detection signals in gas turbine applications
- Operating independently from normal control loops to ensure safety integrity
When unsafe conditions are detected, the board triggers a rapid turbine trip, protecting both equipment and personnel.
