IS215VPWRH2AC GE Mark VI, IS215VPWRH2AC Emergency Turbine Protection Board

Description:

The IS215VPROH2B is an emergency turbine protection panel developed by GE.

The emergency turbine protection (VPRO) board and accompanying terminal strips (TPRO and TREG) provide an independent emergency overspeed protection system.
The protection system consists of three redundant VPRO boards located in a separate module from the turbine control system, which uses TREG to regulate the trip solenoid valve.
For IONet communication with the control module, the VPRO also has an Ethernet connection.
The emergency trip function is provided by the VPRO board in protection module P. Up to three trip solenoids can be connected between the TREG and TRPG terminal blocks.
TREG supplies the positive terminal of the 125 V DC power supply to the solenoid, while TRPG supplies the negative terminal. The turbine can be tripped through either plate.
VPRO provides emergency overspeed protection and emergency stop functions. It manages TREG's 12 relays, 9 of which are divided into three groups of three, operating three trip solenoids via voting inputs.
