Topic: Interfacing relays' coils in quantity (Read 414 times) previous topic - next topic


Hi people!

I'm searching for a shield (or a separate board) I can use to drive a big set of relays' coils with the output pins of the Arduino.

I've got these relay boards that are really nice (you can see a small manual at http://formula9.net/files/8relaycard_manual.pdf); they have the electronics (simple transistor/diode circuit) to drive the coils of 8 relays (230V, 10A), so I can just connect the pins to the board and go.

What I'd like to find is a shield or board that takes the role of that amplifier circuit (for each pin), so that I can use external, heterogeneos relays (more powerful or less powerful).

Any sugestions?

Many thanks!
