Board 6021GPS is a further development of the DCF77 Radio-controlled Clock
Board 6021. The highly accurate synchronization of the Board takes place via the GPS
satellite system, which is available worldwide.
The dimensions of the switching boards correspond to the standard format for Euro-boards
with 3U/4HP front panel (
U = Height Unit / HP = Horizontal Pitch
) for installation in
19" racks:
Some of the system’s basic functions:
•
Synchronization can be realized with only
one satellite
•
Simple operation using
remote software
•
Remote interface on the front panel (RS232 format)
•
Status LEDs
on the front panel

Status output
via two relays (dry contact) for power and synchronization
•
Serial interfaces
(RS232 and RS422 formats)
•
High freewheel accuracy
through GPS-supported regulation of the internal quartz
base

Potential isolation
of the GPS antenna circuit
•
Completely
maintenance-free
system
