IS215VPROH2BC | GE Steam turbine control system

GE IS215VPROH2BC is an LST TMR reheat card used in the Mark V series for steam turbine control systems. However, the IS215VPROH2BLME, which is similar to it, can 

operate within a temperature range of * * 0 ℃ to 65 ℃ * * at rated temperature.

· Protection function: It is a part of the protection core and main tripping circuit, with three sets of three emergency tripping relays and at least two sets of main tripping relays. 

When two of the three relays in the system fail, the turbine will trip.

· Auxiliary control output: including four auxiliary control outputs: electrical lock solenoid valve, oil reset solenoid valve, mechanical lock solenoid valve, and oil test solenoid 

valve. It can perform various tests such as actual electrical overspeed trip test, mechanical trip piston test, etc.

· Application Fields

It is mainly used in steam turbine control systems to monitor and control the operating status of steam turbines, ensuring their safe and stable operation. It is widely used in

industrial fields such as power plants, refineries, and chemical plants where steam turbines are used as power sources.
