Energy Storage	220 µF at 35V

GE DS200SDCIG2A DS200SDCIG2AHB stores energy using two electrolytic capacitors. Together, they provide 220 µF at 35V rating for output hold-up. This energy storage maintains digital outputs during 25 millisecond power interruptions. Therefore, the board prevents false switching in industrial environments.

Design and Integration

Both the GE DS200SDCIG2A and DS200SDCIG2AHB versions share identical I/O circuitry. These boards use six-layer PCB construction with isolated I/O banks for noise immunity. Consequently, the GE DS200SDCIG2A DS200SDCIG2AHB operates reliably from -10°C to +55°C ambient temperature.

For installation, you need M3 screws for the four mounting holes. The board draws 280 mA typical current from the 24V DC supply. Each digital output can drive inductive loads with built-in snubbers. We recommend using separate cable trays for input and output wiring.

Practical Application

This SDCI board manages digital field signals for drive and turbine control systems. It reads limit switches, push buttons, and sensor status continuously. The GE DS200SDCIG2A DS200SDCIG2AHB then sends output commands to relays, solenoids, and indicators. Therefore, it provides reliable digital I/O expansion for GE industrial automation platforms.
