Default cobalt points motors

Hi All,me again......
I have now laid track on new DCC layout and am about to start wiring.My question to you is.... I have a number of ELECTROFROG code 55 Peco points and Cobalt IP ANALOGUE point motors,can i use these motors on dcc layout using 12 volt supply? Also,do i wire these exactly the same way i did on my DC layout(with regard to wires to track)?
Thanks in anticipation of your replies,
Jack

Hi

There is no reason at all why Cobalt Analogue motors cant be used on any layout DCC or DC.

If you want them to be DCC operated you will need an accessory decoder capable of providing a continuous output or use the DCC Concepts AD1 or AD8 stall motor decoders.

If you wish to operate the Cobalt motors from a separate power source then use one that ideally provides 9 volts regulated DC or 12 volts DC. Operation is then via a DPDT toggle switch on the panel connecting to Cobalt terminals 1 & 2. You use the change over contacts on the Cobalt motor 4 & 5 and feed the frog via 6, taking DCC power from the DCC powered rails or DCC bus if you have a bus pair to 4 & 5. If you get a short on the DCC reverse wires in 4 & 5 only.

I have a single Cobalt analogue motor (rest are all digital). I also had some spare ports on a solenoid output decoder. By replacing the DPDT switch mentioned by FB above with a DPDT latching relay with a separate 12v DC supply input, I can drive it via DCC control. Just use one side of the solenoid output to drive one relay coil and the other side to drive the other. You must use a latching relay as the output from the solenoid decoder is only a short pulse and the analogue cobalt needs a constant DC voltage.

That's fine. I just updated my earlier post to include a wiring diagram should any one else be interested in my method.

That document was produced when the first version of the Cobalt was produced. Since then the Cobalt has been completely redesigned twice, but whether it's any more reliable than the V1 I couldn't say.

I have 66 Tortoise motors which have worked without a single fault for many years now.

Sounds like a lot of yankee drum banging . Of course what they dont mention is the price difference, significantly more when purchasing in the UK, an important factor when purchasing high numbers.

I agree - surprised there wasn't a picture of DT!
