Hi
I've just joined the forum. This is my first post, so I apologise if its in the wrong place.
I'm building a bottle-filling machine, and am using a 12V DC relay to switch 220V AC mains across a 1.5A rating n/o relay contact. It will operate a 220V AC solenoid valve of around 1A.
The relay draws about 0.5A, and is operated by a liquid level float reed relay switch.
Can anyone advise me on the value and composition of the 2 spark-suppression capacitors I will need across both the relay contact and the reed relay contact?
If you're interested, I could publish the circuit diagram I 've drawn up for the machine. Its very simple.
