james.wilson Posted November 2, 2006 Share Posted November 2, 2006 your gonna need a psu of some sort as you only have a low current output from your projector. That isnt goint to run any relay. You may be able to get a basic plc that will do this but thats gonna need a psu too although some are 240v. I Doubt your projector has a DC power outlet. securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

bellman Posted November 2, 2006 Share Posted November 2, 2006 but what I am trying to is achieve the same thing without having to use the 12v PSU. Can't be done. some reed relays work of tiny triggers but they can't switch mains, gonna have to bite the bullet and get a psu I'm afraid. either that or hack the projector to draw power from there Regards Bellman Service Engineer and all round nice bloke ) The views above are mine and NOT those of my employer.

james.wilson Posted November 2, 2006 Share Posted November 2, 2006 What else is in this room, maybe something that has 12 ish volts? As bellman says in that projector there will be 12 v somewhere, but it will be soldering iron time securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

Red Fox UK Posted November 2, 2006 Author Share Posted November 2, 2006 There are two sockets on the ceiling, one for the screen, one for the projector - the 12v supply would need to come from somewhere near the projector; and a black brick plugged into the ceiling aint gonna look nice.

Red Fox UK Posted November 2, 2006 Author Share Posted November 2, 2006 Yes, I have a 240v source but how would I use that in conjunction with a 12v trigger the projector gives when it comes out of Standby to On.

james.wilson Posted November 2, 2006 Share Posted November 2, 2006 the projector cant sink enough power to drive a relay, unless you know of a 240v t relay with low voltage starts? securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

Red Fox UK Posted November 2, 2006 Author Share Posted November 2, 2006 So when it comes out of standby, does it switch on 240v to anywhere on the projector where you can tap off??
