GE DS200TCQBG1B DS200TCQBG1BCB 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 DS200TCQBG1B and DS200TCQBG1BCB versions share identical analog I/O circuitry. These boards use six-layer PCB construction with separate analog and digital grounds. Consequently, the GE DS200TCQBG1B DS200TCQBG1BCB 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 RST extended analog I/O board connects field sensors and actuators to a turbine control system. It reads temperature, pressure, and flow signals from RST modules. The GE DS200TCQBG1B DS200TCQBG1BCB then sends control outputs to valves and positioners. Therefore, it serves as a high-density analog interface for GE RST turbine control systems.
