Jintyman Posted April 16, 2014 Share Posted April 16, 2014 I'm just starting on the signalling for my layout and I'm wondering if the DCC Concepts AD1/ AD4 Accessory Decoders will work the colour light signals? If so, can anyone provide me with a wiring diagram at all please? The reason for the question is that I find them so easy to programme and operate and reasonably priced too. I use a Lenz LH100 and a Lenz Compact as a slave, with a 5A Lenz transformer. I'm going to be using the Cobalt point motors as well, although that will be done in stages at £20+ apiece!!!!! Thanks in advance for any help JInty ;-) Link to post Share on other sites More sharing options...
kspoons Posted April 16, 2014 Share Posted April 16, 2014 i don't think they will there is a module sold by dcc concepts by ldt which is specifically designed to drive colour lights signals for the british market. costs about £50 and depending on the complexity of the signal will drive up to 4 signals. i have used these extensively and once you get the hang of them are easy to use. spoons Link to post Share on other sites More sharing options...
Suzie Posted April 17, 2014 Share Posted April 17, 2014 If your decoder can drive a tortoise or similar (which I think the AD series can) then it can drive a 2-aspect colour light signal made from a pair of LEDs in inverse parallel or a 2-leg bi-colour LED in a searchlight configuration with a suitable current limit resistor in series. It is possible to connect other 2-aspect signals up too using steering diodes with the anodes connected to the common cathode (or cathodes connected to the common anode).

Brian Posted April 18, 2014 Share Posted April 18, 2014 No guessing or assumptions, I read the AD1/4 manual which clearly states.... Power Input: Direct from the DCC booster/track output or 12v DC Output voltage: Appx 9.5 V DC with NMRA standard DCC track voltage So its output is dc, its continuous and it's around 9.5 volts. This may mean a slightly lower value of series resistor might be needed in a LED lit signal over what is supplied for 12 volt working. But trial on the AD1/4 would prove the signal illumination brightness. But do remember unlike many accessory decoders the AD1/4 only has one pair of outputs which flip their polarity unlike most acc. decoders that have three outputs + - and C.

Jintyman Posted April 22, 2014 Author Share Posted April 22, 2014 Thanks guys, I've sent an e-mail to DCC Concepts asking the question, I'll post back with their response Jinty ;-) Link to post Share on other sites More sharing options...
Wogga Posted April 23, 2014 Share Posted April 23, 2014 Hi Jinty i have used the LDT decoders which are available from most UK DCC suppliers, should be priced similar to an AD4. https://www.ldt-infocenter.com/dokuwiki/doku.php?id=en:ls-dec-br Link to post Share on other sites More sharing options...
