IS200ISBBG2AAB InSync Bus Bypass PCB

The GE IS200ISBBG2AAB is an InSync Bus Bypass Printed Circuit Board (PCB) designed for GE’s EX2100 Excitation Control Systems and Mark VI Speedtronic turbine control platforms. Its core function is to provide a hardware-level bypass channel that maintains critical excitation control data transmission when the main InSync bus is offline for maintenance, faults, or upgrades, ensuring generator excitation regulation remains uninterrupted and the unit can continue operating without load reduction.
