I want to connect it to the output of a circuit. How do I connect it. It has got the screw terminals for inputs but how do I connect it with my circuit.
No. there is an opening below the screws and as you loosen a screw, you'll see a clamp like affair open. You insert a stripped end of wire in there and then tighten the screw. Give a tug on the wire to make sure it's secure.
