Energy Storage	220 µF at 35V

GE DS200SIOCG1A DS200SIOCG1AEA 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 noisy VME environments.

Design and Integration

Both the GE DS200SIOCG1A and DS200SIOCG1AEA versions share identical I/O circuitry. These boards use six-layer PCB construction with VME bus timing compliance for compatibility. Consequently, the GE DS200SIOCG1A DS200SIOCG1AEA operates reliably from 0°C to +55°C ambient temperature.

For installation, you plug the board into a standard VME64 chassis slot. The board draws 250 mA typical current from the 24V supply. Each analog input provides 12-bit resolution for accurate measurements. We recommend using shielded cables for all analog field connections.

Practical Application

This VME stand I/O board connects field sensors and actuators to a VME-based controller. It reads digital and analog signals from turbine or drive systems. The GE DS200SIOCG1A DS200SIOCG1AEA then sends output commands to relays and solenoids. Therefore, it provides flexible I/O expansion for GE VME64 industrial control platforms.
