6AU1425-2AA00-0AA0 Siemens Programmable Motion Controller SIMOTION D425-2 DP 16 DI/DO
The Siemens 6AU1425-2AA00-0AA0 is a high-precision time message generator from the SICLOCK family, designed to provide centralized, reliable time synchronization across industrial automation networks. Known as the SICLOCK TM25, this DIN-rail mountable device ensures all connected controllers, HMIs, drives, and I/O systems operate on a common, accurate time base—critical for event logging, sequence-of-events recording, batch processing, and regulatory compliance in industries like energy, water/wastewater, pharmaceuticals, and manufacturing.
Unlike standard NTP servers, the TM25 supports multiple industrial time protocols simultaneously, including DCF77 (radio clock), NTP/SNTP, IRIG-B, SINUMERIK time messages, and Siemens-specific time telegrams (e.g., for SIMATIC S7 PLCs). It can receive time from up to three independent sources—such as DCF77 radio signal, GPS (via optional module), or an upstream NTP server—and automatically switches to the best available source with failover redundancy.
With its rugged design, integrated web server, and seamless integration into TIA Portal and STEP 7, the 6AU1425-2AA00-0AA0 is the ideal solution for plants requiring traceable, synchronized time without dependency on external IT infrastructure.
