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).

The antenna lightning protection kit affords additional protection through the use of an impulse suppressor installed in the antenna lead-in coax cable. In the event of a lightning-derived high voltage surge occurring on the coaxial cable, the impulse suppressor activates, short-circuiting the cable directly to the protection ground. Kit contents (all components required to install lightning protection are included): - Impulse Suppressor - Self-amalgamating tape - 2 x N-type Male crimp style connectors to match antenna cable - Crimp Tool to match the above connectors (RG59).
The antenna mounting bracket is an adjustable 500mm powder-coated steel bracket for securely mounting the timing optimized antenna option.
High performance CNT-240 cable, factory-fitted with a TNC-type male connector at one end, and a SMA male connector at the other. Cables are available in standard 15, 30, or 60 meter options. Contact our sales team if you require other custom lengths.
Simplifies the connection of an IED with a BNC connector to a shielded twisted pair IRIG-B wiring loom.
Dual GPS/GLONASS antenna radome that boasts exceptional out-of-band rejection, specifically designed for industrial/static timing environments. The antenna includes a pipe-mounting plinth that is designed to fit the antenna mounting bracket accessory.
