Specifications

Description

DS200SDCCG5A is a Digital Exciter Drive Control Card manufactured and designed by General Electric as part of the EX2000 Series used in Excitation Control systems. The Drive Control Card (SDCC), the main processor board, contains the EX2000's primary control circuitry. It consists of three 16-bit microprocessors and associated circuits coupled via dual-ported RAM. It includes general-purpose interface circuitry that connects with other boards to form various types of excitation systems. This interface circuitry controls and processes exciter and customer I/O. It also expands processing capability via two external dual-ported RAMs. In TC2000 applications, the interface circuitry and three primary microprocessors are utilized for various tasks.
