Discuss 12v Relay in the Security Alarms, Door Entry and CCTV (Public) area at ElectriciansForums.net
Just walk into your wholesalers, I will be flabergasted if they do not have one on the shelf.I presumed you could get them, are there any that are more preferred?
Remember you need a 12v contactor, as you can not run 230v through a panel relay
Because the relay in mounted on the alarm pcb, and to conform to selv, must be kept at alarm voltage potential.
A separate boxed relay must be used
Suggest read the thread again....any idiot..? why ask the question.....? A relay and a contactor are the same thing....there is no difference between the two...?Yes, any idiot knows that, but the OP was specifically asking for a relay to put in a seperate enclosure. Your post suggested that a relay was unsuitable and it had to be a contactor.
Had a hard day,Dave? ....Tazz knows his onions with this gear,and is far from being ^^^^ :bobby:Yes, any idiot knows that, but the OP was specifically asking for a relay to put in a seperate enclosure. Your post suggested that a relay was unsuitable and it had to be a contactor.

Why not? If the relay has a 12V coil and 240V switch contacts what's the issue?
There is a drawing on the packaging fella, come on manOk so I'm in Eddies and have purchased the following... Not being too clued up on relays, can someone tell me please which pin goes to what, so where do I out my 12v feed and 230v in and out.
thanks

Do alarm panels come with din rail mountings?
I’ll argue that statement any time you like.
Ok, its a Castle Enforced alarm, see photos from the instructions.
It says, the IO board says it has a max current output of 70mA, but then below it says the PGM/SAB outputs are 250mA continuous?
Any thoughts as im a little stumped now...

No worries your welcome, we like you thats why it was mild :biggrin:Thank you for the mild abuse, I appreciate that there is a drawing on the back, it would have been more helpful if labelled thats all.
I was presuming that 2 and 7 were the 12v feed and the others were the NO or NC contacts, just wanted some clarification.
Ill stick with this.
2 coil +
7 coil -
1 com 1
3 NO 1
4 NC 1
8 com 2
6 NO 2
5 NC 2
Don't forget you diode connected across the coil to stop the back emf. Reverse polarity connected.
Or you could go for one of the handy little relays.
Just google handy little relay.
Look at the picture he's posted, the diode is already built in to the relay he has bought!
Which is visible in the pic. Provide your own catch diode.Looks to me like an LED
