Description：

IS215VPROH2B is a Turbine Protection Board manufactured and designed by General Eectric as part of the Mark V Series used in GE Spedtronic gas urbine contcolsystems The Turbine Protection Board VPRO) and associated terminal boards (IPRO and TREG) provide an independent emergency oversped protection system. Theprotection system consists of triple redundant VPRO boards in a module separate from the turbine control ystem, contoling the trip solenoids through TREG.The VPRO board in the Protection Module

provides the emergeny trip function. Up to thre trip solenoids can be connected betwen the TREG and TRPG terminal boards. TREG provides the positive side of the125 V dc to the solenoids and TRPG provides the negative side. Either board can tip the turtbine. VPRO provides emergeny overspeed protection and emergeny stopfunctions. I conttols the 12 relays on TREG, nine of which fom three groups of three to yote nputs contolig the three trip solenoids A second TRFG board may bedriven from VPRO through J4.

Product Applications

Steam Turbines: Used for the control and protection of industrial steam turbines, monitoring speed and immediately triggering trip procedures to shut off the steam inlet valves in case of overspeed.

Combined Cycle: This is its primary application scenario, responsible for monitoring gas turbine operating parameters, such as monitoring exhaust temperature protection via thermocouple inputs.

Wind & Energy: The Mark VI/VIe series is also commonly used in distributed control systems (DCS) for large wind turbine clusters and other renewable energy facilities.

Oil & Gas: Used for turbine drive control systems that drive compressors or pumps in oil and gas transportation.

Hydro & Nuclear: Serves as a protective layer for critical rotating equipment in nuclear power plants or hydroelectric power stations.
