RUBIDIUM VD Module:
|
Features |
|
Four built-in amplifiers 1:4 Distribution of LTC, Serial and Telegram Signals Two RS232 Outputs Four RS422 Outputs Compatible with Alpermann+Velte's MTD signal |
| The module VD is a versatile distributor and amplifier. Injected input signals, e.g. signals provided by the MTD system, are available at its four outputs. |
| The VD module is able to distribute / amplify typical signals like:
|
|
(RS232 + RS422, e.g. for reference time) (e.g. to access analog clocks) |
LEDs located on the front of the module and a fault detector relay indicate the present operating status of the module.

| The VD’s main task is buffering and distributing the output signals of GT or GL generator modules. |
| User consoles like the TCU can be connected directly to the VD module.
|
In case of an exclusive processing of LTCor RS485 signals, it is possible to cascade multiple VD modules in order to increase the amount of output sockets.
Analog clocks are accessible via the TELEGRAM protocol. Two-Wire-Mode as well as Four-Wire-Mode is supported.
