OVERVIEW

Time synchronization creates a platform for an entire system comprising wide range of applications to operate in synchronous with time.

The demand for improving the effectiveness of any system in place is met with time synchronization system deployed in the field. Troubleshooting is simplified by the application of time syncing equipments in the event of fault analysis.

SERTEL manufactures GPS based Time Synchronization System Equipments that generates precise time stamp signals that synchronizes various networks of electrical, computer, communications devices such as DCS, PLCs, LANs, Computer Buses, RTUs etc.
