GE DS3800HRRB Relay Output Card

 

The primary function of the DS3800HRRB is to act as an interface between the low-power digital signals from the main processors and the higher-power devices it controls, such as relays. Its key roles include:

  • Relay Output: It takes a low-voltage command from the control system and energizes a relay, which is an electromechanical switch used to control high-power circuits (e.g., to turn on a motor or a solenoid) using a low-power signal.
  • Signal Isolation: The board provides a critical layer of electrical isolation, protecting the sensitive control electronics from the electrical noise and voltage spikes that are common in industrial applications.
  • System Control: It is a key part of the system’s ability to physically command and control external devices, such as motors, pumps, and valves, which are essential for the operation of the turbine.
