IS215VPROH2B

The GE IS215VPROH2B is a VME Protection Assembly designed for the GE Mark VI Speedtronic turbine control system. Also identified as the VPRO Emergency Turbine Protection Board, it is responsible for critical turbine protection functions, including emergency overspeed protection and emergency stop functions.

The IS215VPROH2B operates as part of the turbine's emergency protection system and works with the TREG and TRPG terminal boards to control turbine trip solenoids. The board provides protection independent of normal turbine control functions, helping initiate an emergency trip when a dangerous operating condition such as turbine overspeed is detected.

The VPRO protection architecture supports redundant protection and trip logic for high-reliability turbine applications. The board is equipped with status indicators for operational and diagnostic monitoring and is designed for integration into GE Mark VI turbine control systems.
