About :

This time I was sent a solid-state relay for repair on direct current. I repaired several of them, found a diagram for it. Behind the scenes, I looked at all the transient processes on an oscilloscope and was a little shocked. When applying a control voltage of 5 V to our relay, the rise time and opening of the transistor was approximately 700 µs and the closing time was more than 1.2 ms. So try to apply a control voltage of about 12 V, but with 24 V of the control minus, the secondary part of the circuit can burn out and there will be a large control current. Now you can enjoy some tea and watching this video!))
