Dear all, part of my project is having to OPEN/CLOSE a gas cylinder and so I decided to use a solid state relay - http://www.crydom.com/en/Products/Catalog/m_p.pdf connected to a microcontroller (arduino mega) having its output of the relay connected to a solenoid valve. Since I am not confident in relays, does anyone know if I can just connect the relay to a digital pin, giving it a HIGH or LOW?
I dont know if there can be any Back EMF generated or if I have to coinnect any electronic circuit before the relay.
Thank you
