FUNCTIONAL DESCRIPTION:

IS200EMIOH1AEB is an Exciter Main I/O Board manufactured and designed by General Electric as part of the EX2000 Series used in GE Excitation Control Systems. The Main I/O board is a single-slot, double-height VME-style board that mounts in the control rack. EMIO handles the I/O from the EPCT, ECTB, EACF, and EXTB terminal boards. The I/O includes PT and CT signals. Contact inputs, output relay drivers, and pilot trip relay drives. It also sends logic-level gate pulse signals over the backplane to the ESEL board, which sends them to EGPA in the power conversion cabinet. EMIO handles inputs and outputs from several I/O boards that are cabled to the control rack. Gate command outputs to ESEL and the flashing and de-excitation outputs to EXTB are shown in the following figure. Commands from EMIO to ESEL are transferred over the backplane.
