Optoisolator Driver for Vaccum Solenoid

12/06/2007 4:08 AM

Hi to all!

I wish to know weather MOC3061 can drve the solenoid directly ( without using triac )or not.

The solenoid is operating on 230v AC and of 14 Watt.

I ahve read datasheet of moc3061 but can't find the output current capacity of it.

Anyone who can enlighten me?

Thanks on advance!

The data sheet tells you that this is a device to drive a Triac. It has a capability of short repetitive pulses (some 100usec with a compliance of up to 1A). But the total power dissipated in the triac area is 240mW, that means that if you connect a load to a 230 Vac through this triac, the current that passes will dissipate a power of 240milliwatt. Period. Your relay is 14 W or so. Why don't you connect a triac driver the way they show at the bottom of the data sheet?
