IRIG-B changeover and monitoring module.
- Switcher for VITC signals
- Signal monitor with status indicator
- GPI outputs for error indication
- Optional SNMP and status indication via an internet browser
- Bi-stable signal outputs relays
The PLURA Rubidium SI module is an automatic switchover unit for IRIG-B signals. It analyzes and monitors two IRIG-B sources.
If one IRIG-B source is lost, the IRIG-B output is automatically switched to the other error free source.
Connected with a reference time source, the IRIG-B signal is monitored and analysed in conjunction with this reference time signal.
The module can monitor the following:
- Errors in the IRIG-B.
- Errors in the reference time source,
- Time differences between the two individual IRIG-B sources
- Status information of all input sources.
If an Ethernet module is present in the system, the status and error messages can be queried via a browser or SNMP.
When combined with two of PLURA master generators RUB "GI", a fully redundant fail-safe IRIG-B generator system is possible.
One or both IRIG-B input sources can be acquired from any third party 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).
All programmable functions and the communication between modules are handled 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 via the USB interface of the applicable housing (H1, D1, S1, T1).
The firmware or additionally purchased options are installed via the same USB interface.
With an additional Ethernet module (RUB IE), a standard web browser can access all status information and configuration menus.
Monitoring via SNMP is also possible.
