Power Distribution Module (PDM) - Europe/UK

[Tev62]

If you are looking for a convenient way of powering accessories or heated clothing etc. in an electronically fused way the very low cost (£30) PDM from Marks Motorcycle Parts is just the job.

The live on ignition only connector under the left hand side panel is an ideal trigger for the onboard relay which ensures all circuits are deactivated when the ignition is off.

Ensure the relay module has some weather and moisture protection.

That may be a nice device for someone building a minimalist custom. But I don't like that they use self-resetting circuit breakers which might make troubleshooting more difficult. I also don't like that you are limited to 5 amps. That may work for some accessories, but some loud horns and auxiliary driving lights pull way more than that.

And heated clothing are close to that. Sometimes heated gloves plug into a heated jacket or vest, drawing way more than 5 amps. If there were some 7 amp or 10 amp circuits, it might be more useful.

All kinds of relay modules are available on Amazon and are cheap. You can make your own device like this if you are into that sort of thing. Even delay on or off.

Yes, I am not suggesting that you power circuits greater than 5A on a 5A circuit and if your requirement is for a larger draw you would not use this. The Denali Sound Bomb comes with its own 30A rated relay. I was merely pointing out a handy low cost, small power distribution module.

My inner heated gloves draw 1A on maximum setting and my heated vest draws a maximum of 1.7A so I am well covered in that respect. The circuit board does have a conformal coating spray and if located in the compartment above the battery it would not have to be a waterproof device. Auxilliary driving lights tend to be all LED now and 5A is way more than enough for those.

The heated clothing comes with battery terminal leads with an inline mechanical fuse rated for the garment. I just cut the battery terminals connectors off and wire to the PDM making troubleshooting quite simple. The main aim of this unt is to have multiple outlets live on ignition only. It could power USB ports, Sat Navs, Cameras etc. There are plenty of alternatives but usually at quite a price premium.

You can, I made a simple single relay circuit for my CB with a €9 automotive relay. Even that was a bit upmarket as I wanted a diode protected one. For pure convinience it is hard to beat a £30 five circuit PDM though if that is all you need.

I use a water proof, fuse-protected (2A) USB charging socket under the seat for all devices
(which I rarely use at all). The fact that it doesn’t turn off with ignition isn't a problem
since I won’t leave the phone behind when leavng the m/c in the parking. Not a replacement
for the device described here, but an “intermediary” solution.
