GE DS3800XPEX    Relay Module Card

The GE DS3800XPEX is a Relay Driver Card for the GE Speedtronic Mark IV turbine control system. Its main function is to translate the low-power electrical signals from the system’s processor into the higher-power signals needed to activate and control the electromechanical relays. These relays are critical for controlling functions like switching loads, activating alarms, and managing various start-up and shutdown sequences.


 

Key Functions & Features

 

  • Relay Driving: The DS3800XPEX acts as a switch, specifically a low-side switch, which controls the ground side of a relay coil. This is a common and reliable method in industrial automation because it simplifies wiring and reduces electrical interference.
  • Signal Translation: It takes digital commands from the control system’s processor and converts them into the necessary current to energize the relay’s coil.
  • Protection: The card includes built-in protection mechanisms to handle the demands of an industrial environment. These include overcurrent and thermal protection to prevent damage from excessive current and overvoltage protection to clamp voltage spikes, which are common when switching inductive loads like relays.

Related Components

 

As a relay driver card, the DS3800XPEX works in conjunction with other components of the Mark IV system:

  • Processor Cards: The main brain of the system, like the DS3800HCDA, sends commands to the relay driver card.
  • Relay Logic: The card’s outputs are connected to external electromechanical relays, which then control the power to various loads.
