General Electric IS215VPROH2B Turbine Protection Board

The GE IS215VPROH2B Turbine Protection Board is an advanced, high-performance protection and monitoring module designed for use in GE Mark VI and Mark VIe turbine control systems. It belongs to the globally trusted GE Speedtronic™ family, which is the industry standard for the protection, monitoring, and control of gas turbines, steam turbines, and critical rotating equipment.

As an integral part of turbine protection architecture, the IS215VPROH2B is responsible for acquiring, processing, and analyzing critical protection signals — including overspeed, vibration, temperature, shaft position, and other key parameters — to ensure the safe operation of turbines.

The board continuously monitors these vital measurements and initiates protective actions (such as emergency trip commands) when preset thresholds are exceeded. It provides fast, deterministic protection logic to minimize risk and prevent catastrophic equipment failure in demanding environments like power plants, oil & gas facilities, and chemical plants.

The IS215VPROH2B seamlessly integrates with the VMEbus rack architecture of Mark VI/VIe systems and supports redundant configurations for maximum reliability. It also features advanced self-diagnostics, allowing operators to verify system health and improve maintenance scheduling.
