relay to control appliance power on/off
relay to control appliance power on/off
(OP)
Hi forum! I'm looking where to find a relay too switch on/off a house appliance using 220V and rather low current (for example a light or a small machine) by using a 5V control voltage with max. 30 mA current. Is there a relay with such values? Can I use a microcontroller circuit outputing these values (5V vs. 0V) to use in an application like this??
Can you point me into a relay model i can use for this??
thanks in advance for any answer and sorry for the newbie question (new in electronics, just trying hard...)

check the omron catalogue..
look for miniature relay..i believe they have 5 volts working coil...commonly used in output section of OMRON PLC's....good current capacity ...we used it in powering up relays in heat seal and heat tunnel machines...and cheap too...the only thing is you are going to need a relay socket unless you want to solder it straight to the board which i don't recommned..visit...

use ULN2003 to drive relay from a digital circuit like a microcontroller or even you can use a single transistor.
you can see ULN2003's data sheet on www.ti.com
