Kallaroonian Posted September 18, 2020 Share Posted September 18, 2020 Hi I think I know the answer to this but looking to check others knowledge and experience. Am I right in saying that one Switchpilot output cannot reliably switch two solenoid point motors? But a DCC Concepts ADS nnn can? (specifically an ADS8fx or sx) Thanks Link to comment Share on other sites More sharing options...
WIMorrison Posted September 18, 2020 Share Posted September 18, 2020 Depends on the type of solenoid motors - if you mean peco/seep then you are correct. If you mean fleischmann/Roco then you can switch several together. Link to comment Share on other sites More sharing options...
Kallaroonian Posted September 20, 2020 Author Share Posted September 20, 2020 Thanks. I mean Peco so that's what I thought, cheers Link to comment Share on other sites More sharing options...
mjenderby Posted November 15, 2020 Share Posted November 15, 2020 I'm just struggling with this. I have 2 crossovers with both points (Seep solenoid motors) connected to a single ads2fx output. One works but the other needs 2-3 attempts to switch. This is no good when using computer route setting☹ Spent all afternoon trying different wiring to no avail. Connections are short run, and close to the DCC power source. Don't even work when motors not attached to point/board. So my answer is "it depends"!

KingEdwardII Posted November 15, 2020 Share Posted November 15, 2020 I don't use solenoid motors - I use MTB MP1 motors in the main - slow action. I switch pairs of points like crossovers using a single channel on my DCC accessory decoder (Digikeijs DR4018 in my case). Works a treat, 100% reliable. The current draw of these motors is fairly low - max 150mA - so that a pair never tries to draw more than is available from the accessory decoder. Yours, Mike.

mjenderby Posted November 16, 2020 Share Posted November 16, 2020 PS I tried a different unit with similar results. Given one pair of points work, maybe it's an issue of variability with the SEEPs. What is certain is that the switching power diminishes significantly if you try to drive 2. In the event I had a spare output so now separately powered. This means switching is very positive and there are no worries about partial switching :-) Cheers Mark Link to comment Share on other sites More sharing options...

Another thing to consider is the DCC system voltage as this will effect the charge voltage of the capacitors on the ADS units. (The higher the DC volts, the higher the capacitor volts resulting in a higher output pulse voltage) Best Regards, The DCCconcepts Team Link to comment Share on other sites More sharing options...
Butler Henderson Posted November 16, 2020 Share Posted November 16, 2020 A solution I used was to have the accessory module drive relays which connected a CDU to the requisite PMs and via a diode matrix as appropriate. 1 Link to comment Share on other sites More sharing options...
