The GE IS200VSPAH1A IS200VSPAH1AAA Speedtronic Turbine Control PCB serves as a protection card for Mark VIe systems. This board monitors critical turbine parameters including speed and temperature. You will find it in gas turbine and steam turbine control cabinets. It provides hardware-based overspeed detection independent of software logic. Therefore, this unit ensures fail-safe turbine shutdown during emergency conditions.
The GE IS200VSPAH1A IS200VSPAH1AAA Speedtronic Turbine Control PCB measures 250 mm in height and 170 mm in width. Its depth reaches 42 mm for chassis mounting. The unit weighs approximately 0.88 kilograms. It contains one 32-bit processor and three independent speed comparators. Sixteen discrete inputs accept 24 VDC signals from field devices. Additionally, you get fourteen status LEDs for diagnostics.

Internal Architecture and Energy Storage
The GE IS200VSPAH1A IS200VSPAH1AAA Speedtronic Turbine Control PCB stores moderate energy in its power filter. Electrolytic capacitors hold approximately 480 microfarads total capacitance. A 32-bit processor runs protection logic at 120 MHz. Three independent hardware comparators monitor each speed channel continuously. These comparators trigger directly without software intervention for safety. Sixteen optocouplers isolate the discrete inputs from the processor. Eight solid-state outputs provide high-speed shutdown of control valves. Fourteen LEDs show power, run, speed, and output status clearly.
Connection Interfaces and Wiring Details
You will find two 50-pin ribbon cable headers on the board edge. Connect these headers to termination boards for field wiring. The GE IS200VSPAH1A IS200VSPAH1AAA Speedtronic Turbine Control PCB also includes a 10-pin JTAG header. Use shielded twisted-pair cable for all speed sensor connections. Connect each magnetic pickup to its dedicated speed input channel. Fourteen LEDs indicate power, run, speed, and output conditions. A green PWR LED lights up when the board receives 5 VDC. A green RUN LED flashes when the processor executes logic normally. A red TRIP LED indicates an overspeed condition has occurred.
Installation and Configuration Steps
You mount this board onto a metal chassis with six screws. First, drill six 5 mm holes matching the mounting pattern. Then, secure the board using M4 screws with lock washers. Connect the 5 VDC and 24 VDC power wires to the terminal blocks. The GE IS200VSPAH1A IS200VSPAH1AAA Speedtronic Turbine Control PCB consumes 600 mA from the 5 VDC supply. Connect the ribbon cables to the termination boards for all signals. Use the Toolbox software to configure overspeed trip setpoints. Set the number of speed sensor teeth for each pickup. Configure the voting logic (1-out-of-3 or 2-out-of-3) for tripping. Program the output mapping for emergency shutdown valves. Download the configuration to the board’s flash memory. Test each overspeed channel with a pulse generator before turbine startup.
