        Features:

        • Interface Between the Protection Module and Emergency Trip Solenoids
        • Provides Emergency Overspeed Protection with Triple Redundant Architecture
        • Operates in Conjunction with TREG and TRPG Terminal Boards in Mark VI Systems
        The IS215VPROH2B operates as the Turbine Protection Board in the Mark VI protection module, providing reliable emergency trip functionality for gas turbine overspeed protection. It continuously monitors turbine speed through dedicated inputs and executes emergency shutdown commands by controlling up to three trip solenoids connected between TREG and TRPG terminal boards. TREG provides the positive side of 125 V DC to the solenoids while TRPG provides the negative side, and either board can independently trip the turbine. Seamless protection coverage is standard with the IS215VPROH2B, however using the triple redundant configuration with three separate VPRO boards (R8, S8, and T8) will allow continuous protection even if one board is powered down or replaced while the turbine is running. The IS215VPROH2B has made improvements in protection reliability over previous designs by incorporating complete electrical isolation between redundant channels within the protection module.

        The IS215VPROH2B provides essential protection functions critical to turbine safety, and is a vital component of the emergency overspeed system, directly affecting the safe operation of the overall gas turbine control system. One to three IS215VPROH2B boards are deployed per protection module depending on the desired redundancy level. The IS215VPROH2B occupies a dedicated slot in the protection module and communicates through resident onboard communications rather than the VME backplane when installed in the protection rack.

        For Triple Redundant Protection applications, the Mark VI System requires three IS215VPROH2B boards installed in the protection module. In addition to standard single board operation, the redundant configuration also performs independent voting logic. The IS215VPROH2B triple redundant system executes protection decisions using the relay control circuitry specified in the board design. Using this method, the protection system continually monitors the health of all three VPRO boards through diagnostic communications. If the system detects that one IS215VPROH2B board is no longer providing valid protection output, the remaining two boards maintain full overspeed protection capability, and diagnostic status is reported to the operator interface and controller event lists.

        The IS215VPROH2B GE Turbine Protection Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Description
        The GE IS215VPROH2B is a high-performance Turbine Protection Board manufactured by General Electric as a core component of the Mark VI Speedtronic control system. This IS215VPROH2B board is specifically designed to provide an independent emergency overspeed protection system, operating within a standalone module separate from the primary turbine control. By utilizing a triple redundant architecture (R8, S8, and T8), the IS215VPROH2B ensures that critical safety functions remain active even during hardware maintenance, allowing for a single board to be replaced while the turbine is running without jeopardizing the entire system's integrity.

        In practical industrial environments, this IS215VPROH2B is purpose-built to handle catastrophic mechanical failure risks caused by uncontrolled turbine acceleration. It solves the problem of potential system downtime and equipment damage by providing a dedicated emergency trip function that acts independently of the main controller. For instance, in gas turbine power plants where synchronization and temperature stability are vital, the IS215VPROH2B provides backup synchronization check protection and manages exhaust over-temperature via nine thermocouple inputs, ensuring the turbine shuts down safely if critical thresholds are exceeded.

        Technically, the IS215VPROH2B functions by controlling twelve relays on the TREG terminal board. These relays are organized into three groups of three to perform "voting" logic, which ultimately controls the three trip solenoids. By coordinating with TREG and TRPG terminal boards to provide the necessary 125 V dc power to the solenoids, the IS215VPROH2B eliminates the risk of nuisance trips or failure-to-trip scenarios. This robust design makes the IS215VPROH2B an essential safeguard for maintaining the operational safety and reliability of GE Speedtronic gas turbine systems.

        Technical notes
        The VPRO board in the Protection Module provides the emergency trip function. Up to three trip solenoids can be connected between the TREG and TRPG terminal boards. TREG provides the positive side of the 125 V dc to the solenoids and TRPG provides the negative side. Either board can trip the turbine. VPRO provides emergency overspeed protection and emergency stop functions. It controls the 12 relays on TREG, nine of which form three groups of three to vote inputs controlling the three trip solenoids.

        VIEW ALL FAQS
        What is the IS215VPROH2B board used for?
        The IS215VPROH2B is a turbine protection board developed by General Electric for the Mark VI Speedtronic gas turbine control system. It is designed to provide independent emergency overspeed protection and turbine trip functionality, ensuring safe shutdown in critical operating conditions where turbine speed exceeds safe limits.
        How does the protection system in IS215VPROH2B work?
        The protection system is built around triple redundant VPRO boards, operating independently from the main turbine control system. These boards work together with associated terminal boards (TPRO and TREG) to control trip solenoids. TREG supplies the positive 125 V DC to the solenoids, while TRPG provides the negative side. Any of the VPRO boards can initiate a trip signal, ensuring that the turbine can be safely shut down even if one component fails.
        What role does the VPRO board play in turbine safety?
        The VPRO board is responsible for executing emergency trip commands and emergency overspeed protection. It controls a set of relays on the TREG board, where groups of relays use a voting logic system to determine when to activate the trip solenoids. In total, it manages multiple safety-related inputs and outputs, including analog current signals and thermocouple inputs used for exhaust over-temperature monitoring.
