GE DS200NATOG2A LCI Attenuation Card

The card’s function is a cornerstone of system safety and signal integrity:

  • Attenuation: The primary role of this board is to reduce the amplitude of a signal. In the context of an LCI, it takes high-amplitude signals from voltage and current transformers on the power bridge and scales them down to a safe, low-voltage level (e.g., +/- 10V). This is essential because the sensitive analog-to-digital converters (ADCs) on the control cards cannot handle the raw, high-level signals. The DS200NATOG2A provides this precise and necessary scaling.
  • Protection and Isolation: Beyond simple scaling, this card provides a crucial layer of electrical isolation. By acting as a buffer, it separates the low-voltage control circuitry from the noisy, high-power environment of the LCI. This protects the control cards from dangerous voltage transients, electrical noise, and ground loops, ensuring system reliability and safety.
  • LCI System: This card is a key component of a Load Commutated Inverter (LCI) drive. These systems are used for high-power applications, such as the static starting of large synchronous generators and motors. The attenuated signals provided by the DS200NATOG2A are vital for the control system to accurately monitor the motor’s performance, allowing it to make precise, real-time adjustments.

In essence, the DS200NATOG2A is the “translator” between the powerful, high-voltage world of the LCI’s power bridge and the precise, low-voltage world of its digital control system. Without it, the system would be blind to its own performance and vulnerable to electrical damage.
