The GE part number IS200ERIOH1A is an EX2100 Regulator Main I/O Card. It is a crucial component of GE’s EX2100 Excitation Control System. Its primary function is to serve as the primary interface between the system’s central processor and the various sensors, actuators, and other devices in the field, specifically for the regulator’s core control functions. ⚙️
Function and Key Features
The EX2100 is a digital control system that regulates the output voltage of a generator. The ERIO board is the main hub for all the signals that are needed for this control.
- Main I/O Interface: The board provides a wide range of analog and digital I/O channels. This includes inputs for sensors that measure voltage, current, and temperature, as well as outputs to control devices like relays and contactors.
- Signal Conversion: It contains the necessary circuitry to convert the analog signals from the field into a digital format that can be processed by the system’s central processor. It also converts digital commands from the processor into analog or digital signals that can be used to control field devices.
- System Integration: The ERIO card works in conjunction with the main control card (like a DSPX) to form the complete excitation control system. It’s the primary point of connection for all the field wiring related to the regulator.
- Robust Design: Like all GE industrial control components, it’s built to withstand the harsh conditions of a power plant.
Applications
The IS200ERIOH1A is a legacy component primarily found in power generation facilities. It is an essential component for:
- Generator Control: It provides the data necessary for the EX2100 system to precisely control the generator’s voltage and reactive power.
- Plant Automation: It is an integral part of the automation system for the generator, helping to manage startup, shutdown, and normal operation by providing a means of controlling and monitoring auxiliary equipment.
- Fault Detection and Protection: It receives signals from various sensors, which are used to detect faults and initiate protective actions to ensure the safety of the generator and the electrical grid.
