Hi,
?
We got this question in our ticket system as well ?
?
Here is what I answered:?
Q: Before buying many YD6016LN and/or ES modules I need to know how many I can daisy chain on the LocoNET bus.?
A: LocoNet specifies a theoretical maximum of 47 devices on the bus. In Practice that means however that 40 is a good workable limit. Digitrax used to advertise that as well.
But... nowadays Digitrax advises to use a LNRP ( Repeater ) if the number of connected devices exceeds 20 ? ( maybe to sell repeaters ? )
That is why our solution with extendable LocoNet devices ( the YD6016LN series ) is so interesting.
One can see such a combo as one single LocoNet feedback device with a variable number of inputs.?
The base unit provides 16. every extra YD6016ES adds another sixteen, without counting as extra LocoNet device. So one can create a single LocoNet feedback with 16 upto 96 inputs !!
Q:Since the YD6016LN derives its power from LocoNET and subesquent ES modules appear to get power from the LN module it's a crucial piece of information.?
A: Our modules take about 25mA each. So it depends on the Command Station's LocoNet drive how many can be directly connected. Our YD7001 provides about 800mA hence a total of about 32 modules? (LN+ES) can be supplied with power.? For more modules, we advise the use of a so-called LocoNet supply. That is a device that injects another 1 Amp of 12V supply.
Q:?I also use several Digikeijs DR5097 LN hubs to provide multiple paths to serveral other LocoNET devices. So there is a lot of load on the LocoNET bus.
A: The DR5097 LN hubs are completely passive, so do not add to load.?
