PRODUCT INFORMATION
Product Overview
The General Electric IS200EDCFG1AED is a Feedback Board engineered for Mark VI control systems. It measures field current and field voltage at the Silicon Controlled Rectifier bridge. This board operates within gas, steam, and wind turbine automated drive systems. It connects directly with the EISB board located inside the turbine control panel. Voltage isolation on the board is accomplished through dedicated fiber-optic transmission channels. Two optical links provide high electrical noise immunity during operational monitoring. Hard-clad silica optical cabling supports distances up to ninety meters. Plastic fiber cabling supports operational lengths up to ten meters. Seven selector settings allow scaling of the measured bridge feedback voltage.
The IS200EDCFG1AED incorporates two relays, an inductor coil, six integrated circuits, and discrete transistors. Dual heat sinks dissipate thermal loads across the board assembly. External direct current power enters the board via two-pin connector J16. Pin one accepts positive twenty-four volt direct current for the onboard converter. Pin two connects to the common reference line for power conversion. A single status indicator labeled IMOK displays normative operational health. Physical connection points include a two-position plug labeled P1 and a four-position input plug.
