 Compatibility and Instructions

1. System Compatibility: **ABB UNITROL Excitation Platform**, used to collect SSI encoder/velocity sensor signals and send them to the excitation controller for speed closed-loop, excitation loss protection, and speed limit logic.
2. Material Characteristics of the Same Series: Belongs to the ABB **3BHE××R0001** excitation board card family. The board card is of a PCB insert card structure and is directly inserted into the system backplane, not an external independent module.
