I am doing a project using this same actuator and a similar set up where I do not need know position and I am powering it with a 12V battery. Instead of using the two relays, is it possible to just use a DPST relay like this one: http://search.digikey.com/us/en/products/RT444012F/RT444012F-ND/1427665
If this is not possible can someone explain to me how to wire the DPDT relay for this application?
and last question: What do relay data sheets mean by "Turn On Voltage (Max)"? If this is over 5V and I am controlling the relay with a signal from a pin on the arduino, does that mean I am going to need to use an op amp to open the relay if it is a normally closed relay?
Thanks in advance for the help.
