TTM 01-G Compact Substation Clock

TTM 01-G Compact Substation Clock

The TTM 01-G is a reliable and accurate GNSS (GPS/GLONASS) DIN rail-mounted clock with sub-microsecond timing that is used to synchronize IEDs (Intelligent Electronic Devices) in the power industry. As with all Tekron GPS clocks, the TTM 01-G has electrically isolated outputs, providing excellent noise immunity and transients protection. The TTM 01-G supports Network Time Protocol (NTP), PTP (IEEE® 1588v2-2008) and, IRIG-B and is perfect for installations with limited mounting space.
