GE IS215VPROH1B Emergency Turbine Protection Board
Functional Description
The IS215VPROH1B Emergency Turbine Protection (VPRO) board and associated terminal boards (TPRO and
TREG) provide an independent emergency overspeed protection system. The protection system consists of
triple redundant VPRO boards in a module separate from the turbine control system, controlling the trip
solenoids through TREG. VPRO also has an Ethernet connection for IONet communications with the control
modules.
The VPRO board in the Protection Module <P> provides the emergency trip function. Up to three trip
solenoids can be connected between the TREG and TRPG terminal boards. TREG provides the positive side of
the 125 V dc to the solenoids and TRPG provides the negative side. Either board can trip the turbine. VPRO
provides emergency overspeed protection and the emergency stop functions. It controls the 12 relays on
TREG, nine of which form three groups of three to vote inputs controlling the three trip solenoids.
