GE IS200EAUXH1ABB Exciter Auxiliary I/O Interface Board

Product Description

The GE IS200EAUXH1ABB is an exciter auxiliary I/O interface board for the GE Speedtronic Mark VIe control system, used together with EX2100e generator excitation control units. It serves as the signal bridge between the excitation controller and field devices, collecting analog measurement signals and discrete interlock feedback for excitation regulation, protection and status monitoring. This ABB suffix version is the complete assembled revision of IS200EAUXH1A, widely deployed in power plant generator excitation cabinets and used as critical spare parts for maintenance and system retrofit.

Product Functions

• Collect voltage, current and temperature analog signals from the exciter power unit
• Receive discrete contact signals for excitation interlock, fault feedback and ready status
• Transmit control commands and excitation status signals between the main controller and exciter unit
• Signal conditioning, filtering and surge isolation to suppress EMI interference in high-voltage cabinets
• Support excitation overvoltage, overcurrent and loss-of-field protection logic judgment
• Standard rack plug-in design, compatible with Mark VIe backplane and EX2100e excitation system

Application Scenarios

• EX2100e generator excitation systems for steam turbines and gas turbines
• Power plant generator set Mark VIe control and protection cabinets
• Hydroelectric generator and large synchronous motor excitation control systems
• Oil & gas and petrochemical large generator control equipment
• Spare replacement and repair of existing GE Speedtronic Mark VIe racks
