GNSS Satellite Clock – TTM 01-G

Key Features:

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.

• Supports GPS and GLONASS
• Independently isolated outputs
• Isolated power supply
• High output power line drivers
• Low noise characteristics due to balanced pair distribution
• UTC and LST with user defined DST options
• Remote configuration over Ethernet
• Configuration security
• Remote firmware upgrades
• Enhanced security and encryption that exceeds NERC CIP requirements
