The GE part number IS200EMIOH1A is an EX2100 Main I/O (Input/Output) Card. It’s a crucial component of the EX2100 Excitation Control System. Its primary function is to provide the primary interface between the system’s central processor and the various sensors, actuators, and other devices in the field.
Function and Key Features
The EX2100 is a digital control system that regulates the output voltage of a generator. The EMIO 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, contactors, and other actuators.
- 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 EMIO 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.
- Robust Design: Like all GE industrial control components, it is built to withstand the harsh conditions of a power plant.
