Energy Storage	220 µF at 35V

GE DS200TBQAG1A DS200TBQAG1ABB 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 DS200TBQAG1A and DS200TBQAG1ABB versions share identical I/O circuitry. These boards use four-layer PCB construction with isolated I/O banks for noise immunity. Consequently, the GE DS200TBQAG1A DS200TBQAG1ABB 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 analog input includes software selectable ranges. We recommend using shielded cables for all analog field connections.

Practical Application

This RST terminal board connects field devices to an RST turbine controller. It terminates digital and analog signals from sensors and actuators. The GE DS200TBQAG1A DS200TBQAG1ABB then routes conditioned signals to the host processor. Therefore, it serves as a flexible termination interface for GE RST turbine control systems.
