PLURA GPS modules output an accurate serial protocol that contains time and date information, a seconds pulse, and two 10 MHz reference signals.
PLURA Rubidium series SR module analyzes and monitors all the contents of two reference signals.
If a reference signal is lost, the output is automatically switched to the other error free reference source.
The module monitors and analyzes the real-time sources, and the quality of the incoming signals.
The module can monitor the following:
- Errors in the reference time sources.
- Time difference between the two individual reference signals.
- Status information of all input sources.
When a SR module is combined with two reference signal generators, such as PLURA RUB GPS 10 MHz, a fully redundant failsafe reference signal can be processed.
One or both reference sources can also be acquired from external third parties devices.
In the event of a failure the signals can be switched autmatically or manually. The changeover is completed with bistable relays.
The relay contact remains in its last position even if power is lost.
The relays are mounted on a separately installed circuit board, so that even when physically exchanging a module the signal flow can continue without interruption.
LEDs located on the front of the module indicate the operating status.
Built-in GPIs can be programmed to signal errors or other pre-programmed warnings.
The backlit keys on the front of the module can be programmed to suit the user specific needs (e.g. a key could be programmed to manually switch incoming sources).
Where necessary a double redundant systems (e.g. two buildings that both have their own redundant systems).
Different GPS or DCF receivers can be used as inputs.
A programmable application on how each reference signal (whether stationary or a mobile receiver) is assigned during a changeover, is included with this module functionalities.
The SR module can also be used for series and or parallel redundancy applications.
All programmable functions and the communication between modules can be set with the included configuration software.
The operating status of the module is available at any time via a status monitor function.
The status request is made using a PC software using the USB interface of the applicable housing (H1, H3, S1, T1).
Firmware upgdate for the frame and other modules can be set up via the same USB interface.
With the optional Ethernet module (RUB IE), Standard web browser can utilized for all status information and configuration menus.
Monitoring via SNMP is also possible.
