GE IS215VPROH2B Turbine protection plate

GE IS215VPROH2B is an emergency turbine protection board designed by General Electric (GE) specifically for gas turbine control systems, belonging to the Mark VI series modular components. The following is a comprehensive analysis based on multi-source information:

· Core functions and application scenarios

· Name and functional positioning

· Full name: VME Protection Assembly

· Core functions:

· Emergency overspeed protection (EOS): Three redundant VPRO boards are used to achieve turbine overspeed protection independent of the main control system, triggering trip solenoid valves to prevent equipment damage.

· Analog and thermocouple inputs: Supports 3 analog current inputs (such as AC1A/5A) and 9 thermocouple inputs for monitoring key parameters such as gas turbine exhaust temperature.

· Redundant communication: Interact with the main controller through the Ethernet interface (IONet) to ensure the reliability of data transmission.

Application scenarios:

· Gas turbine control: As a core component of emergency protection systems, it is used for turbine equipment in industries such as petrochemicals and power.

· Industrial automation: Provide independent fault safety mechanisms in distributed control systems (DCS).

· Technical Characteristics

· Hardware Design:

· VME bus architecture: using 6U high VME board, compatible with rack mounted installation of GE Mark VI system.

· Diagnostic function: The front panel is equipped with LED indicator lights, which display real-time power status, communication connections, and fault information.

· Electrical parameters:

· Input: AC1A/5A analog current (accuracy ± 0.2%), thermocouple signal.

· Output: Supports standard signals such as DC0-10V/0-20mA, used to drive trip solenoid valves or other actuators.

· Power supply: 24V DC power supply, power consumption ≤ 3W.

· Communication protocol:

· Supports IONet 10Base2 Ethernet (H2 version with 3 BNC interfaces) and RS-232 serial communication.

· system compatibility

· Terminal board matching: It needs to be used with TREG (trip solenoid valve power board) and TRPG (trip solenoid valve negative plate), and can connect up to 3 trip solenoid valves.

· Redundancy design: the third mock examination Redundancy (TMR) architecture is adopted to ensure the correctness of protection logic through voting mechanism
