IS200ERIOH1A GE Regulator MAIN I/O Card
Description:
IS200ERIOH1A is GE EX2100 series Regulator MAIN I/O Card. IS200ERIOH1A provides the l/O interface for customer and system l/O in the EX2100 Regulator Control systems (simplex and redundant). For simplex applications, it is mounted in ERBP and interfaces customer l/O signals for the EPCT and ECTBG2 terminal boards. lt also interfaces system I/O signals for the ERDD and the EROC for simplex applications.

For redundant applications, IS200ERIOH1A is mounted in the ERBP (M1) and also in the ERRB(M2/C) and interfaces customer l/O signals for the EPCT and ECTBG1 terminalboards. It also interfaces system I/O signals for the ERDD, EROC, and the IS200ERRR Exciter Regulator Redundant Relay board (ERRR) for redundant applications.

The ERIO, EPCT and ECTB boards are interconnccted through two 25-pin connectors to ERBP (M1 in redundant) and also to ERRB (M2/C) in redundant applications. One ERlO each is provided in the M1, M2, and C control sections.

An onboard ficld programmable gate array (FPGA) is used to control data acquisition and storage into dual port memory (DPM). The DPM is accessiblc by the DSPX board from the backplane.

The ERIO, EROC and ERDD boards are connected through the ERBP (simplex) and ERRB (redundant) backplanes, The ERlO and ERRR are interconnected through one25-pin connector in the backplane (ERBP, ERRB).
