The TTM 01-G is a reliable and accurate GPS and GLONASS (GNSS) clock with sub-microsecond timing that is used to synchronize IEDs (Intelligent Electronic Devices) in the power industry and other industries where precise and reliable timing is required. As with all Tekron GPS clocks, the TTM 01-G has electrically isolated outputs, providing excellent noise immunity. The TTM 01-G supports both NTP/SNTP and PTP (IEEE 1588v2).
