GE IS200TDBTH6A IS200TDBTH6AAA 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 turbine control environments.
Design and Integration
Both the GE IS200TDBTH6A and IS200TDBTH6AAA 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 IS200TDBTH6AAA 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 discrete terminal board manages digital field signals for turbine control systems. It reads limit switches, push buttons, and relay status continuously. The GE IS200TDBTH6A IS200TDBTH6AAA then sends output commands to solenoids, contactors, and indicator lamps. Therefore, it provides high-density discrete I/O for GE turbine control panels.
