The GE IS200TSVOH1B IS200TSVOH1BAA termination servo board connects servo valves to the Mark VI control system. This board provides signal conditioning and drive capabilities for hydraulic actuators. You will find this unit inside a standard Speedtronic turbine control rack. It translates low-level control signals into valve positioning currents.

Physical Layout and Component Arrangement
The GE IS200TSVOH1B IS200TSVOH1BAA termination servo board uses a rigid epoxy substrate. Two power amplifiers occupy the center section of this board. Six filtering capacitors surround these amplifiers for noise reduction. Two large storage capacitors provide energy for sudden current demands. Two backplane connectors anchor this board securely into the Mark VI rack. A front terminal block connects directly to servo valve wiring.
Functional Features and Integration
This termination board converts digital position commands into analog drive signals. It monitors the actual valve position through built-in feedback circuits. The GE IS200TSVOH1B IS200TSVOH1BAA also includes overcurrent protection on each output channel. Consequently, it prevents damage to both the board and the servo valve.
Installation and Safe Handling
Always disconnect power before wiring the servo valve connections. Hold the GE IS200TSVOH1B IS200TSVOH1BAA firmly by its non-conductive edges. Push the board straight down until both backplane connectors lock into place. Then route valve wires to the appropriate terminal block positions. After installation, perform a servo tuning routine through the Mark VI software interface.
