GE DS3800HLIC GROUP ISOL LOGIC INP

 

The primary function of the DS3800HLIC is to provide electrical isolation for groups of input signals. In an industrial environment, multiple sensors and devices are often powered by different sources, which can lead to electrical interference, noise, and ground loops. The DS3800HLIC prevents this by:

  • Galvanic Isolation: It uses a physical or electrical barrier (such as optocouplers) to ensure there is no direct electrical connection between the input signals and the main control board.
  • Signal Integrity: By isolating inputs in groups, the board ensures that the signals received by the main system are clean and accurate, which is essential for the reliable and safe operation of a turbine.
  • Protection: It safeguards the Mark IV control system and other connected devices from electrical faults that could originate from the input side.
