IS215VPROH2B GE Module Parts Mark VI Emergency Turbine Protection Board
The GE IS215VPROH2B is an Emergency Turbine Protection (VPRO) Board designed for GE SPEEDTRONIC Mark VI turbine control systems. It provides an independent protection layer responsible for emergency overspeed detection, emergency-stop functions, and turbine trip control.
The VPRO protection system uses three redundant boards installed in a protection module separate from the main turbine control system. These boards work with the TPRO and TREG terminal boards to monitor turbine operating conditions and control emergency trip solenoids.
The IS215VPROH2B is a lower-power version of the VPRO board. Unlike the H1A/H1B versions, it supports only one TREG terminal board. This distinction is important when selecting replacement components for an existing Mark VI installation.
