YD6016LN-RC inputs going to waste

 
Edited

The circuit breaker topic went?in an unexpected direction, but I thought I needed some confirmation about another essential requirement - detection. Hence the new topic.
Adding in Railcom to a layout design does require at least 1 feedback module for each booster.

In general the YD6016LN-RC looks like it will fit my requirements for a Loconet based detector that is both a 3mA current sensor and a Railcom reporter.
If I read it correctly it has 16 inputs that would be tied to one booster. That's a lot of inputs that can go to waste. I would rarely use more than 8 of them and often less.
For example in comparing it to the Digitrax BDL-168, it has 16 inputs that can be grouped into groups of 4 inputs that can each feed different boosters or circuit breakers if needed. Quite flexible.

Also what is the YaMoRC solution for reversing loops?
 

Oldngrey,

The use of boosters as reversing devices is rather archaic, from the very early days of DCC, precisely because it usually ends up wasting most of the output of a booster. YaMoRC doesn't seem to have an autoreverser?yet, I wonder if the Digikeijs DR5013 Digireverse?or a PSXX-AR?would work with the YaMoRC YD7403, and if?the YD7403's short circuit trip timing can be adjusted to accommodate?an auto reverser or older PSX board downstream of it?

This brings up another interesting topic. The European manufacturers seem to have gone to detectors where you run track current through the detector device, often with up to 16 detection sections requiring heavy gauge wire, while, with the notable exception?of Digitrax, US manufacturers use coil-based detectors that can be located at the block location, with thin gauge telephone wire going back to the sensor board that interfaces with LocoNet, C/MRI, LCC, cab bus, etc. I suspect this again has to do with American layouts tending to be more spread?out, with long runs, versus more compact European layouts with more dense block setups for passenger stations and automation. The thing is, you have to run track current through the detector in order to do Transponding or RailCom, requiring the heavy gauge wiring to the detection device.

Also if I use a YD7403 booster as a reversing loop automatic polarity switcher, then do I need a YD6016LN-RC just to detect the reversing loop? Doesn't that waste 15 inputs?

Sorry about that. I edited my post to remove my comment about the booster as a viable reverse loop switch. I've got a Digitrax DR5013 on order to test it out with the DR5033 booster. There are still some Digikeijs products for sale if you look for them.
I've got one reverse loop on the lower deck that is rather complex since it's not connected by 1 turnout.
Hopefully YaMoRC will have a solution when I need to wire up all the staging yard reverse loops on the top deck maybe next year. Meanwhile we have what we can get.

Incidently I've been using Digitrax BDL168s but got around the problem by using their RD2 (remote diode) in series with the block. All blocks within a power district come back to a single board. The RD2 allows thinner cable back to a BDL168 (I use alarm cable). To be honest the price of the NCE BD20 was a bit high.
As you can see I have a lot of wiring to rip out.

I also hope that all these questions are of general interest.
 

Well, making the DR5033 autoreverse was one of my biggest mistakes.

It not only caused/causes quite some problems with customers who do not really understand reverse-loops. But also one does not detect incorrect wiring as the booster autoreverses.

So the YD7403 will not have that "feature".

?

Further, the DR5013 contains RailCom circuitry and delivers (occupation) feedback and RailCom data over LocoNet. So no extra feedback modules needed there.
