REP4507 0 Posted August 17, 2014 G-Day, It has been so long since I have had to work with DVR alarm outputs that my regular supplier went out of business so the guy I knew and trusted is no longer available to me. What I want to do is trigger some 240V mains powered lights but I cannot find a relay that will run off my DVR 12V alarm output. Can someone find me something? Preferably an eBay item.

Billy_ICU 0 Posted August 17, 2014 In the U.S. we would search for a relay based on its activation voltage - in this case 12 volts or 12VDC. And next by the number of switch contacts - SP = Single Pole, DP = Double Pole. And by if it is just making / breaking one connection or two. ST = Single Throw, DT = Double Throw. So you could search for: 12VDC DPDT Relay Then look at the contact amperage and voltage ratings. Also in the U.S., relays are typically to be mounted on a printed circuit board, the same thing called a solenoid is used for automotive, and relays designed to be mounted in an electrical wiring box for building wiring are called "contactors"! So perhaps: 12VDC DPDT Contactor Or: 12VDC DPST Contactor Of course Europe and the UK probably have different names for all this??? Also check in a home automation store for gizmos which are designed to turn on/off lights in a home. Wall plug-in modules and replacement wall switches. That might be a better and safer way to go - they may have some sort of controller which will accept a relay connection. Names for this stuff in in U.S. are X10 (old), INSTEON, Z-Wave, Home Automation.) Share this post Link to post Share on other sites
REP4507 0 Posted August 28, 2014 How about a: JQX-10F-2Z Electromagnetic Relay. Would this work? Share this post Link to post Share on other sites
the toss 0 Posted August 30, 2014 That relay would do the job but I would not recommend it. The problem with it is the plug-in base. It looks like connection to the base is by soldering to the pins which if not illegal for 240V is certainly not a good idea when you have your low voltage coil connection in such close proximity. Try Jaycar. They have a similar one with well spaced spade connectors . Share this post Link to post Share on other sites
