GPS Clock

Time Code Generator TCG 01

The Tekron TCG 01 provides a time synchronization solution with superb timing accuracy (better than 100 nanoseconds to UTC), designed for synchronizing multiple industrial control and SCADA devices, including protection relays and remote telemetry units.

Outputs are electrically isolated allowing outputs to feed directly to areas with different earth potential zones without compromising the overall site earthing security.

TCG 01 outputs include:

• 1 AM IRIG-B
• 2 TTL/RS422/ST fibre/HV switch (programmable signals)
• 1 RS232 (serial strings and programmable signal)
• Network Time Server
• 2 Event recording inputs

TCG 01 Multiport Unit outputs include:

• 4 AM IRIG-B or TTL/RS422 (programmable signals)
• 1 TTL/RS422 (programmable signal)
• 2 Event recording inputs
