GE DS200ADGIG1A DS200ADGIG1AAA stores energy using one electrolytic capacitor. This capacitor provides 100 µF at 35V rating for output hold-up. Consequently, the board maintains output voltages during 20 millisecond supply interruptions. Therefore, actuators remain stable through brief power dips.

Design and Integration

Both the GE DS200ADGIG1A and DS200ADGIG1AAA versions share identical I/O circuitry. These boards use four-layer PCB construction with separate analog and digital grounds. Consequently, the GE DS200ADGIG1A DS200ADGIG1AAA 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 loads up to 10 mA maximum. We recommend using shielded cables for all analog field connections.

Practical Application

This analog I/O board connects sensors and actuators to a drive or turbine controller. It reads temperature, pressure, and flow signals from field devices. The GE DS200ADGIG1A DS200ADGIG1AAA then sends control outputs to valves and dampers. Therefore, it serves as the analog interface for GE industrial control systems.
