Energy Storage	220 µF at 35V

GE DS200TCQFG1A DS200TCQFG1ACC 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 DS200TCQFG1A and DS200TCQFG1ACC versions share identical analog I/O circuitry. These boards use six-layer PCB construction with separate analog and digital grounds. Consequently, the GE DS200TCQFG1A DS200TCQFG1ACC 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 extender board adds additional analog channels to a turbine control system. It reads temperature, pressure, and flow signals from field sensors. The GE DS200TCQFG1A DS200TCQFG1ACC then sends control outputs to valves and positioners. Therefore, it expands analog I/O capacity for GE turbine control systems.
