Q) You are offering a Loconet Repeater Module LNRP.

Is it an RailSync Booster, too?

There is no description in the PDF-File about this attribute.


A)
The LNRP boosts (and separates) the Railsync "Standard" outputs from the master command station ("Protected" Railsync), so if there is a problem with this separated "Standard" Railsync copy, the master Command Station is unaffected along with other devices like track boosters that need good Railsync copies.

This boosted Railsync is also over-current protected and the LNRP will turn off an overloaded "Standard" Railsync and automatically retry re-powering, so when the fault clears the "Standard" Railsync is restored.

This is useful in systems that have plugs that may short the Railsyncs to e.g. ground during operation, or if the wiring is simply overloaded.

In the same way, the LocoNet "data" part of the cable wiring is protected on the Command Station side, so if the "Standard" side has a LocoNet data problem, the LNRP will amputate or disconnect just this data part from the "Protected" command station side.

Once the data fault clears, the LNRP will automatically restore data connection, All the fault states detected are indicated on the LEDS.
