The IS200ERIOH1A board is manufactured by GE for the EX2100 excitation regulator and the entire Mark VI family, providing an I/O interface for customers and system I/O. It provides these functions for simplex and redundant voltage regulation control systems. For simplex applications, I/O is installed in the ERBP (Excitation Regulator backplane) and provides an interface for customer I/O signals from the ECTBG2 terminal board and EPCT terminal board. The IS200ERIOH1A is also capable of connecting EROC (Excitation Regulator option card) and ERDD (Excitation Regulator Interface and Dynamic Discharge) system I/O signals. For redundant applications, it also connects system I/O signals for ERRR (Excitation Regulator redundant relay).

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

FAQ about IS200ERIOH1A
What is IS200ERIOH1A?

The ERIO board provides I/O interfaces for system I/O and customer I/O in the EX2100 regulator control system. It serves both redundant and simplex applications, each with slightly different functionality and connectivity.
What is the EX2100 excitation control system to which this I/O card belongs?

The EX2100 excitation control system, manufactured by General Electric, provides advanced management solutions for new and retrofit gas, steam or hydroelectric power generation. It combines hardware and software elements to ensure system safety and perform operations such as flame detection, signal scaling, and more. The EX2100 is designed to operate efficiently alongside GE’s Speedtronic Mark VI. It provides keyboards, thermistor systems, and more.
