Hello,
I have a pitch valve controller that can controls a series (upto 8) of 12V 130 Ohm solenoids. I want to replace these solenoids with more powerful 12V 16.4 Ohm solenoids. My idea is to include some sort of interface electronics between the existing controller and the new series of powerful solenoids. This interface would use the original solenoid signals from the controller to power a series of relays in order to power the heavier solenoids.
I purchased a SainSmart 8 Ch relay board thinking I can connect the outputs of the controller to either the inputs of the board or solder directly to the relays of the board.

I did however pop the fuse on the controller since the relays had a 70 ohm impedance, too much current I suppose.
Am I over thinking this? Is there a simpler solution? Perhaps a buffer?
Thank you for your suggestions.
Daniel
