GE IS200TDBTH6A IS200TDBTH6ABC stores energy using two electrolytic capacitors. Together, they provide 470 µF at 35V rating for output hold-up. This energy storage maintains digital outputs during 30 millisecond power interruptions. Therefore, the board prevents false switching in Mark VIe environments.
Design and Integration
Both the GE IS200TDBTH6A and IS200TDBTH6ABC versions share identical discrete I/O circuitry. These boards use six-layer PCB construction with isolated I/O banks for noise immunity. Consequently, the GE IS200TDBTH6A IS200TDBTH6ABC operates reliably from -15°C to +60°C ambient temperature.
For installation, you need M4 screws for the four mounting holes. The board draws 500 mA typical current from the 24V DC supply. Each digital output includes overcurrent protection for field devices. We recommend using separate cable trays for input and output wiring.
Practical Application
This VIE discrete terminal board manages digital field signals for Mark VIe turbine control systems. It reads limit switches, push buttons, and relay status continuously. The GE IS200TDBTH6A IS200TDBTH6ABC then sends output commands to solenoids, contactors, and indicator lamps. Therefore, it provides high-density discrete I/O for GE Mark VIe control panels.
