IS200EDCFG1B

General Electric Speedtronic Mark VI IS200EDCFG1B is a Direct Current Feedback Card (EX2100). The function of IS200EDCFG1B is to manage bridge dc voltage and current feedback. At the SCR bridge, the board measures field voltage and field current. Voltage isolation and noise immunity are provided through a fiber-optic link between the EISB board in the control panel. There are two plug connectors on the IS200EDCFG1B. As an input, these are denoted P2 (two-position plug) (4 position plug.) There are multiple high-voltage electrolytic capacitors on the board, as well as other types of capacitors.

Six integrated circuits, a coil inductor, several transistors, and two relays are included on the board. Two heat sinks are added to the board to allow excess heat to be quickly dissipated. It's also worth noticing that the board has seven bridge voltage scale-down selectors marked on it.
