4 REL1000: Error Relay Module
The REL1000 error relay output is connected to the TTL TIME_SYNC output of the reference clock (GPS,
GLONASS ...). If the internal reference clock has been synchronized by its source, the relay will switch to mode
"NO" (Normaly Open). In error case the relay switches to mode "NC" (Normaly Closed).
If the system isn’t equipped with a second clock and RSC switch unit, the relay can be switched by 10MHz or
PPS to monitor these signals.
