Siemens 6DD2920-0AR1 Safety Relay Control Module

Siemens 6DD2920-0AR1 is a transformer assembly (Trafobaugruppe) used within the SIMADYN D drive family. It is described as an SA61 transformer built into the SA60 synchronization module, aligning the SA60/SA61 configuration with an integrated transformer component in the system. The part is cataloged under Siemens’ SIMADYN D line and appears in distributor listings as 6DD2920-0AR1, indicating its role as a transformer module rather than a standalone control relay. Designed for use in Siemens automation hardware, this module fits the SA60 synchronization module configuration (SA61) to complete the transformer assembly within the SIMADYN D architecture.
