Hi John
Yes, I think that should be right, I was just thinking that I never get a reliable voltage when I measure, but I don't have a 5033, only a DR5000.

I was comparing the voltage at the output of the DR5000 with the output of the DR5033 at the connection points on the units, not taken from a point on the track.? They should be similar if both power supplies are set at 19V?

Hi John
Not sure you will get a reliable measurement from a multimeter off the track because there will be DCC data modulating it?

Hi,
I have just wired up a DR5033 and using the provided power supply set at 19 volts, the measured voltage at the track output terminals is only 10.4 volts.? Is this what is to be expected oe should I be getting the 14 volts track voltage as provided by the DR5000 ?

Hi James,
Confirmed both power supplies set on 19V.

Make sure for power supply¡¯s are set on the same voltage.

I am moving this message from the CHAT to just a normal message for this user. Hello Everyone Thank you for letting me join the Forum this year. I hope everyone is safe and well.
I am building a loft layout? and am using Fleischmann track which has three way points.
I really would like the 4018 x 4 to connect all my points single points I understand. But how do i wire up the 3 way points to work. I do have the Digikeijs Dr 5000.
Looking forward to hearing from you all with some Help.
Thanking you in advance

Feedback modules DR4088LN-OPTO; switch track, 2-wire track
re page 14 pdf downlaod - Feedback modules DR4088LN-OPTO; switch track, 2-wire track
what does switch track mean ?
on same diagram right side booster power source, does it matter if the blue and red wires are reversed polarity?
i presume that blue wire is common - return negative, yes i know dcc sends signals on both + and -minus side.
anyone???

Hi Doug.?
Just looking at the cost .
And what is available in Australia first? at the moment .
The other is.
Tam Valley USA looking? there as well at signals and detection boards?
Also looking at Train Tech UK systems?
With NCE I got a quiet a bit so? I will use this? for running .
My main thing is detection. signals changed as train passes . And to show on computer what has happened?
Or state on the diagram?
Just have to wait till everything's starting and restrictions lifted at the moment.?
Andrew?

I can't remember which power supply I used, they come with a mesh cover so have to be mounted in a box of some kind, it is like this?
That is Newark in the USA, I'm sure there are others.
Just look for a regulated supply with enough current capacity, as that will keep the voltage constant. My home layout uses a 13.8v 7A supply that was meant for home CB radios and other stuff that is used in cars. Another power supply uses a pair of 12v supply boards that came out of a piece of testing equipment.?
I used double pole latching relays because on one module I was switching pairs of Fulgurex motors and they take too much current for the DR4018 outputs, and I wanted a manual override for if there were control problems, so there is a multi way switch which disconnects the DR4018 and connects push switches in its place. This mattered as the it is a junction module and stops the whole modular setup if it fails. Another module uses Lenz decoders for turnouts and when running off the DR5000, it will only give out short pulses (on Lenz they are 10 seconds long) so I used the relays to keep the power on the motors. Note latching relays are no good for solenoid motors, as they stay on once the coil is turned off.

Let us know how you get on will be very interesting. ?As I said I still use the NCE on my display layout but am considering changing that in the future, the NCE is a good bit of kit but it is very restrictive.
I am even tempted to see if the next stage might be the installation of detection, but that a little off as it would require rewiring and isolation as a project.
All the best

Good eye there, yes that was the they the layout was wired in 1994. One Common for all S/M's.
Normally you would bring all the commons back and thinking of doing that. So far it is working as the S/M's are firing one at a time.

Thanks Dennis!? Nice, neat, well designed arrangement!? Pictures were very helpful!? I noticed that you did not have a common connection to each output of the 4018.? How are you wiring the commons from the atlas switch machines?? One connection to the common of one output and the rest connected in parallel to a "common bus" near the turnouts?

More of a Distribution Block.
They come either as a 2 x 4 or 2 x 8 but can be reconfigured with a jumper wire as a 1 x 8 or 1 x 16.
Supplied with one end connector or you can just solder wires to the the "A" & "B" pads.
This Photo shows the 2 block on the right two 2 x 4 blocks. One is marked "DCC" and the other is "12 VDC"
This allows me to disconnect the interface wires easily.
One the Left side is two of the 2 x 4's configured as one 1 x 16. I did this to align the block wires with the inputs to the DR5088RC? You will see jumpers on the "A" & "B" end blocks, this makes it a 1 x 8 each and a jumer between the two blocks to make it as a 1 x 16. Only one common connection to the DR5088RC.
The? 2 x 8 Block is show, both blocks come with the standoffs.
These are double sided boards with each side being one solid copper plane.
Next Picture shows a club members layout using the 2 x 8 Blocks being used to connect all his drops instead of using a Buss Wire, He did not want to do troubleshooting on his back.
Several railroads around this area are using these blocks and developed by one of the club members.

Thanks for your reply Mike!? I'll admit that I'm a real novice when it comes to electronics.? My previous layout simply used Atlas switch machines in parallel with a circuit with a CDU and the power supply.? Lighting is something I will consider in the future but initial plan is set up the new layout for turnout control with DCC.? Just to let you know, I live western US.? A few questions:
Can you tell me the brand and model number of your industrial supply?? Makes sense to purchase one supply that can operate multiple 4018's through a bus as I likely use at 6 4018's for just turnouts.
What is the advantage of using relays between the supply bus and turnouts??
Street price for an Atlas snap relay is $12.? Is there a cheaper alternative that is plug and play or simple set up??
Thanks!

My DR4018s run off my 12v d.c. bus which is supplied from an industrial 5A regulated power supply. It also supplies structure lighting and other 12v electronics, the DR4018 supplies signal heads and relays that operate slow motion switch machines, but not direct to switch machines.
For wire size and solenoid motors more important is that the resistance is low enough to allow enough current to flow to operate the motors. A close motor can use smaller wire than a farther one. The rating is not so important because the wire is only under load for a fraction of a second at a time.

I will post something tomorrow showing the blocks I use.

Thanks Dennis!? Not sure what you mean by breakout blocks?? Is this a terminal block or distribution block?
|
It should work, I have a few crossovers and wired them together.
22 gauge is fine, just tried 18 gauge solid and it does fit. Stranded 18 gauge might be iffy.
Connect the DR4018 DCC inputs in parallel. I use breakout blocks as I don't like putting 2 wires in each connector hole.
Dennis

Thanks Dennis, very helpful!? A couple more questions:
Can I, for example, connect 10 turnouts to a 4018 (6 individual and 2 crossovers with each pair of turnouts on a single switch)?? This is an HO switching layout and I would only be activating one turnout or one crossover at a time.
Will a 22 gauge wire fit inside the output connections on a 4018?
How are multiple 4018 connected to the buss or directly to the DR5000?
Thanks!
