2XV9450-1AR22 | Siemens | SICLOCK TM Plant Central Clock

Description

The 2XV9450-1AR22 SICLOCK TM Plant Central Clock is a time synchronization controller designed for production facility automation, part of Siemens’ modular, parameterizable SICLOCK system. It enables precise time synchronization across setups ranging from single PLCs to large-scale factories, with dedicated adaptive components for production device alignment. Key synchronization capabilities include external wireless time reference via global GPS and Germany-based DCF77 signals, ensuring accurate, consistent timing across industrial environments.

This controller features 1 RS422 interface and 1 RS485 interface with a maximum transmission rate of 187.5 kbit/s. It has a front protection rating of IP65 and a general protection type of IP20, with CE certification for compliance. As a central clock solution, it supports tiered deployment: for large factories with multiple network stations and strict timing requirements, it integrates with factory bus-based SICLOCK TC 400 or SICLOCK TS central clocks; for small to mid-sized facilities, it can pair with alternatives like the SICLOCK TC 100. The device operates as a synchronizable, unbuffered software clock, delivering reliable, scalable time alignment to support seamless automation workflow coordination.
