Key Technical Specifications

This GE IS200TSVOH1B IS200TSVOH1BCC board operates from a 24V DC power supply. It provides 8 servo valve control channels for turbine systems. The unit measures 22 cm in length, 16 cm in width, and 4.5 cm in height. Its total weight reaches 0.7 kg without any packaging materials.

The GE IS200TSVOH1B IS200TSVOH1BCC includes 8 analog output channels for valve positioning. Additionally, it features one 50-pin ribbon connector for host interface. A single 6-pin terminal block connects the DC power input. The board contains 8 output drivers, 1 FPGA, 8 voltage regulators, 8 LED indicators, 16 resistors, and 12 capacitors.

GE IS200TSVOH1B IS200TSVOH1BCC stores energy using one electrolytic capacitor. This capacitor provides 100 µF at 35V rating for output hold-up. Consequently, the board maintains valve positions during 20 millisecond power interruptions. Therefore, actuators remain stable through brief voltage dips.

Design and Integration

Both the GE IS200TSVOH1B and IS200TSVOH1BCC versions share identical servo control circuitry. These boards use four-layer PCB construction with isolated output banks for noise immunity. Consequently, the GE IS200TSVOH1B IS200TSVOH1BCC operates reliably from -10°C to +55°C ambient temperature.

For installation, you need M3 screws for the four mounting holes. The board draws 200 mA typical current from the 24V DC supply. Each output channel can drive servo valve coils directly. We recommend using shielded cables for all analog output connections.

Practical Application

This servo terminal board controls turbine servo valves for fuel, steam, and water regulation. It receives position commands from the turbine controller. The GE IS200TSVOH1B IS200TSVOH1BCC then sends precise analog outputs to each valve. Therefore, it enables accurate control of turbine actuators in GE control systems.
