AN-66A-00.PDF
IRIG B is a time code, which allows devices across the world to synchronize with a common time source to a resolution of one millisecond. IRIG B allows each device to synchronize with the frame received
Time Synchronization in Electrical Systems
Time synchronization for substations with integrated protection- and system control functions, as well as data collection require a target architecture that distributes synchronized time in several ways.
How can we achieve time synchronization for Easergy MiCOM P14x
The IRIG-B signal is connected to the board on the back of the relay. The timing information is used to synchronize the relay''s internal real-time clock to an accuracy of 1 ms.
APPLICATION NOTE IRIG-B Time Sync
The IRIG-B to IEEE1588 converter allows 7SR5 to use an existing on-site IRIG-B amplitude modulated (AM) time signal source for applications where the latest IEEE1588 PTP time protocol or SNTP is not
