【 Function Description 】


The IS200ERIOH1AAA board is manufactured by GE for the EX2100 excitation regulator and Mark VI series as a whole, providing I/O interfaces for customers and systems. It provides these functions for a simple and redundant regulator control system. For simplex applications, I/O is installed in the ERBP(excitation regulator backplane) and provides the customer I/O signal interface to the ECTBG2 end board and EPCT end board. The IS200ERIOH1AAA is also capable of interconnecting system I/O signals for EROC(Excitation Regulator TAB) and ERDD(Excitation Regulator Interface and Dynamic Discharge). For redundant applications, it also interfaces the ERRR(Field Regulator Redundant Relay) system I/O signals.



The excitation regulator I/O is connected to the EROC and ERDD boards via the ERBP or ERRB backplane, the former for single applications and the latter for redundant applications. In addition, the ERIO is connected to the ERBP and ERRB via two 25-pin connectors, and to the EPCT and ECTB. FPGA(Field Programmable Gate Array) controls the storage and data acquisition to DPM(dual port memory). This particular unit is a revised version of the original part, denoted by the "A" at the end of the model number.
