GE IS200VPROH1BEF Mark VI Turbine Protection Board in stock

GE IS200VPROH1BEF is an emergency overspeed protection board for GE Mark VI Speedtronic gas and steam turbine control system. It forms a triple redundant independent overspeed safety protection loop, separate from the main turbine control logic to improve unit safety and reliability.

This board is equipped with IONet Ethernet communication port and LED status indicators on front panel, with conformal coating to resist dust and moisture in power plant environment. It is installed in Mark VI turbine control rack, widely used for turbine protection cabinet maintenance, spare parts replacement and power plant control system retrofit projects.
