GE IS215VPROH2BC

The IS215VPROH2BC is a VME-format emergency turbine protection board for GE Speedtronic Mark VI turbine control system, commonly shortened as 215VPROH2BC in inquiry. This IS215VPROH2BC executes independent emergency trip and overspeed protection logic, separate from the main control processor, and it adopts TMR triple modular redundant 2oo3 voting architecture to avoid spurious turbine trips. The IS215VPROH2BC communicates with other Mark VI boards via IONet Ethernet, and it pairs with matching TREG / TRPG terminal boards to drive trip solenoids and emergency shutdown circuits.

This IS215VPROH2BC carries on-board relay circuits for hardwired trip output, which can cut off fuel and activate turbine ESD when detecting overspeed and critical fault conditions. The conformal coated PCB of the IS215VPROH2BC provides stable performance in power plant control cabinets. Front status LEDs indicate power, run and fault alarms for fast on-site troubleshooting. It records protection trip events and diagnostic data for post-fault analysis.

The IS215VPROH2BC is widely deployed on GE gas turbines, steam turbines and generator sets in power plants and oil & gas compression stations. The Mark VI Speedtronic platform including this IS215VPROH2BC is fully discontinued. Most available IS215VPROH2BC units are tested surplus spare parts for planned overhaul and emergency replacement of legacy turbine protection racks.
