Just looking for some advice on choosing the transistor and diode for switching a relay with an arduino. I'll be switching the relay with the arduino 5V. The motors that will be powered are 24VAC two phase induction motors. The manual states a maximum of 1.35A @ 24VAC so I assume these: http://australianrobotics.com.au/products/relay-spdt-sealed should do the trick but, please, correct me if I am wrong!
I am not sure how to choose the transistor and diode, however! Any help would be greatly appreciated :)
