GE IS200VAICH1B IS200VAICH1BED stores energy using two electrolytic capacitors. Together, they provide 220 µF at 35V rating for output hold-up. This energy storage maintains analog outputs during 25 millisecond power interruptions. Therefore, actuators remain stable through brief voltage dips.
Design and Integration
Both the GE IS200VAICH1B and IS200VAICH1BED versions share identical analog I/O circuitry. These boards use six-layer PCB construction with separate analog and digital grounds. Consequently, the GE IS200VAICH1B IS200VAICH1BED operates reliably from -10°C to +55°C ambient temperature.
For installation, you need M3 screws for the four mounting holes. The board draws 300 mA typical current from the 24V DC supply. Each output channel can drive loads up to 20 mA maximum. We recommend using shielded cables for all analog field connections.
Practical Application
This analog I/O board connects field sensors and actuators to a turbine controller. It reads temperature, pressure, and flow signals from turbine systems. The GE IS200VAICH1B IS200VAICH1BED then sends control outputs to valves and positioners. Therefore, it serves as a high-density analog interface for GE turbine control systems.
