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.


The layout of the EMIO board with LEDs is shown in the first figure, the EMIO Board. The Power LED is connected to the 5 V dc power, and the Status LED is connected to the IMOK output from the FPGA. There are no jumpers, fuses, or cable connectors on the board. All cabling from the I/O boards is connected to the control backplane (EBKP). Connector P1 provides communication with the other control boards over the backplane, while P2 provides the interface to the I/O signals through cable connectors located at the lower part of EBKP.
