11.6.27 CES - Chassis Expansion Slot
Standard Basic Configuration:
Error relay contact module for error indication
of clock faults. DFK Connectors (3-pin CO/NO/NC).
Additional available signals via
BNC female connector:
- PPS
- 10 MHz
- other signals on request
These Signals are generated by the pre-connected
clock.
The 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
switched to mode "NC" (Normaly Closed).
