SIEMENS 6DD2920-0BB0为SIMADYN D平台AUL2触发监控逻辑板，属于TM15成套单元的组成部分，配合AL0、AH0、AM0板卡协同工作。该模块负责晶闸管整流桥脉冲时序分配、触发逻辑管理，实时采集功率单元反馈信号，执行脉冲封锁与跳闸保护逻辑。

SIEMENS 6DD2920-0BB0 is the AUL2 trigger monitoring logic board of SIMADYN D platform, part of TM15 assembly, cooperating with AL0, AH0 and AM0 boards. It handles thyristor bridge pulse timing distribution and trigger logic management, collects power unit feedback signals and executes pulse blocking and trip protection.

SIMADYN D产品线早已停产，6DD2920-0BB0是大功率直流传动、冶金轧机主传动、汽轮调速励磁装置的刚需备件，板卡自带硬件快速保护回路，在脉冲丢失、缺相、短路故障时可快速封锁输出，规避功率器件烧毁风险。

SIMADYN D platform is obsolete. 6DD2920-0BB0 is critical spare for high-power DC drives, rolling mill main drives and turbine excitation & governor systems. It integrates hardware fast protection circuit to block pulses rapidly on pulse loss, phase loss and short-circuit faults to protect power semiconductors.
