Product Support for: Mobile Decoders -> 1 Amp Economy Wired Decoder, 2 Functions, Z Scale (DZ123)

Your Athearn example uses the DH123/143 series with the AT clip option, can the DZ123 be used for Athearn older diesels? I am interested because of the small space in S2/4 models. Is the 1 amp DZ123 an option I can use? It is possible that the DZ123 could be used in the older Athearn switchers, but the most important issue will be how much electrical current that the locomotive requires. If the locomotive's stall current is below 1 amp, then the DZ123 can be used. Otherwise, the locomotive motor will eventually, sooner or later, destroy the decoder by drawing ...

I have this N-scale Proto A/B unit. I went to install the decoder in the A unit to the headlight, its an LED. My question is that once it was wired up and place on the track, I hit my headlight function and the light lit up then burnt out. This is my first wired decoder I ever installed with a head light. Can you tell me how to properly wire the led headlight to the DZ123 decoder so the light doesn't burn out? In looking at the DZ123 Decoder sheet, it suggests that I check the Decoder Manual for ...

This article courtesy of Ken Bessler, concerning installation of a decoder into earlier Kato C4400W's.  Current produiction of these locomotives use DN163K1C or similar board replacement decoder.I wanted to convert my 2 new Kato AC4400CW's to DCC but there were several problems:1) The recommended PnP decoder, DN163K1a has a chip right where a shell component is. Using this decoder requires shaving off the plastic retainer clip under the exhaust stack. IMHO this is not good as it leaves too little support for the stack.2) My dealer was out of stock of the PnP decoders.3) A quick look inside the loco shows ...

In the DZ123 mobile decoder, if CV03 and CV04 (acceleration, deceleration) have been programmed for momentum, will momentum remain active when the decoder is then used in analog mode with pure (not pulsed) DC? Yes.

What do I need for DCC control of a Walters Cornerstone Swing bridge? Image Courtesy Wm. K. Walthers We do not have any direct experience with this particular bridge but after a little research, this is what we recommend.The instruction sheet which comes with the 933-1050 Motorizing Kit is quite vague.  "The unit runs on DC power.  Hook the wires up to the DC contacts on a transformer with a maximum voltage of 12.  If you hook it up to a variable speed transformer, do not exceed 12 volts.  The gear ratio is 320:1."  That said, it is still a ...

Many thanks to Bob Dattore for this application note!This app note details using a DN142 decoder for the installation.  This decoder is no longer in production but the following decoders would work as well:  DN135D, DN163, DZ123, DZ125, DZ143.  Any decoder that is small enough to fit could be used.The Problem:  Atlas RS1's (and RS3's & RSD4/5's) are hard to install Digitrax decoders in. There is no easy drop-in or light board replacement with back-emf capability.I have installed several Atlas Dual Mode decoders in these popular hard to fit narrow, low hood diesels with ease, by replacing the original light ...

There was a time when every mobile decoder installation was a custom installation. In those early days, we were just feeling our way along, trying to find ways to make the existing supply of decoders fit into locomotives which had been designed in a different era. Fortunately, things have changed along the way, and in many cases, the Digitrax Decoder Selection Guide will list your locomotive. But many locomotives are not listed because they are too new or are too generic for a special listing. So, from time to time, you will have to "wing it" just a bit to ...
