Din rail connectors linked?

uksparks · Oct 24, 2014

Hi,

ok to follow on from my 12v relay question, I know how I want it all connected.

The next part of the jigsaw is that I need to mount everything on a dinrail.

i presume you can get these, what I need is din rail connectors where I can join say 6 together so that I have 6 common neutrals or lives etc?

do you know what I mean and if so can you pointe in the direction of where to get them.

i have never panel building if this is what you could vaguely call it do not clued up on what's available.

Tom how the hell is that supposed to work when you have a live bypassing your contactors?
You need to draw it out as a schematic mate, it'll make a lot more sense

It is Friday night...

This is my very quick sketch of what I think you are trying to achieve,

Now which one do you think another electrician would be able to pick up and understand what the circuit should do?

I'll explain...

1. 230v supply to main switch
2. Live from main switch goes to 6A MCB
3. The MCB feeds the permanent live connectors / common rail / permanent love to PIR's
4. The neutral from the main switch feeds the neutral bar that feeds the PIR's
5. The neutral from the main switch also feeds both contactors, so is connected to them for pulling them on purposes only
6. Take another live from the MCB and put it on to the relay, and from the relay take it to both the contactors so have a line and neutral to pull it on.
7. The live the feeds the contactors is only live when the alarm goes off and the 12v feed closes the relay.

Looks right to me, thanks for that

.

other than my very poor attempt at drawing this up, do you think it's not a bad option and should work ok?

It'll work fine, I've done it before a few times to override multiple PIR zones with timers and switches etc.
But I would usually tend to put a 0.5A mcb or similar in to fuse the coil circuit seperately, it's not strictly necessary though.
