Siemens 6DD2920-0AL0 AUL2 trigger monitoring logic module for SIMADYN D system, used for thyristor pulse triggering and hardware protection monitoring in high-power converter drive systems.

Product Overview

Siemens 6DD2920-0AL0 is an AUL2 trigger monitoring logic module under the SIMADYN D control platform. It is compatible with SAV21 and SAV22 power racks, responsible for generating thyristor firing pulses and real-time monitoring of pulse status. It can rapidly identify pulse loss and commutation failure, providing hardware interlock protection for high-power converters.
