Hi

i wanted to take a second opinion regarding the impending rewire of my layout. I have ready to connect:

Alpha power
Digikeijs DR5000 controller
Alpha box (to two alpha Centrals)
PSX1 Circuit Breaker to spit ACC / Trk Bus
Digikeijs 4088LN Detector
DCC Concepts Bus filters

other info - all cobalt digital ip or ss motors.

My wish is to have a separate track/ accessory bus and I propose to use the psx1 to achieve the split. 

In the experts opinions, am I right in my expectation that the correct order of connection is:

DR5000 to
DCC Concepts Bus Filter to
Alpha Box / Alpha Power to
PSX1

Then split acc bus and track bus:

- track bus to feature a Digikeijs 4088 detector unit and finally the end of bus DCC Concepts bus filter
-Accessory bus to all cobalt turnout motors

I think this is correct but wanted a second opinion. Also, would I need a bus filter at the end of the accessory bus and also the track bus?

Thanks for any advice.

Andy

Can you draw a diagram, I think what you describe is wrong but am not totally clear on what is connecting what from your description 🙁

Sorry I was very unclear but this is what I’m hoping to achieve to split the bus into a separate accessory and track bus using the psx1 outputs to serve that purpose. But I’m unclear on where to place the bus filters. Should the first go straight after the dr5000 but before the alpha box? And for the last filter on the bus, would I need one on the end of the accessory bus AND one on the end of the track bus. I hope that’s a bit clearer. Thanks for any advice.

I don't know these Alphas Boxes and how they connect but the principle of 2 busses is that you protect the track bus with a power breaker such as PSX and feed the accessory bus directly from the command station which is not what you show. The idea is that if you have a track short then you can still switch the ac accessories, in you case a track short would cause the PSX to trip and that would cut the power to the accessory bus also.

I suggest that you feed from dR5000 into PSX and then to track. You also feed from DR5000 to Alpha box and Accessory bus but (see below)

You would be best to call DCC Concepts and have a chat on how to connect the Alpha box to the DR5000 as the Alpha box is using one RJ12 connection and the pin out isn't described where I can find it easily - it *may* plug directly into the booster output on the DR5000, but it *may* not and only DCC Concepts can give the definitive answer.

I appreciate the response Iain. Thanks. I take your point that if the PSX went out both buses would be down. It was my understanding that on the PSX only one set of outputs is protected (those furthest from the input on the board) and that the alternate outputs adjacent to the inputs are essentially throughputs. Certainly demands more research. Thanks

That is correct on the PSX, but again isnt what you show - the 4 x connectors together are simply 2 x power in and 2 x power out, they can go to the accessory bus, the 2 x connectors at the far end are the protected outputs and should go to the track doing this gives you the 2 busses that you (rightly) desire.

It is connecting the Alpha gear in that i am not qualified to give advice upon as I don't use any of it, I just use a computer screen to do all my switching (and just let the program do it 99% of the time anyway)

I’m with you. Hope to some point delve into the world of automation as your layout has been an source of inspiration.

when you get there give me a shout - can I ask what the Dr4088 is for if you are not planning automation?

On automation this might interest you 🙂

I got it as I was planning on hooking up to itrain and using this for feedback when the time came. Thought it prudent to wire the track this way now to make things easier later. Thanks.
