GPS Clock

TekTime TTM 01 GPS Clock

The TekTime TTM 01 GPS Clock provides an economic time synchronization solution with excellent timing accuracy (sub-microsecond to UTC), designed for synchronizing industrial control and SCADA equipment, including protection relays and remote telemetry units.

Navstar GPS satellites are used to generate extremely accurate output pulses and time codes, providing options for outputs including the choice of:

• 2 TTL level, independently programmable or
• 1 Amplitude Modulated IRIG-B (B12x) output or
• 1 RS232 level pulse plus serial time string output

The TekTime TTM 01 GPS Clock is factory programmed to customer specified output pulses, standardized time codes (eg IRIG-B, DCF77) and serial time strings with a configuration interface module allowing simple programming in the field.
