I am looking to by a relay for my Arduino microcontroller but am first trying to find out if a single channel on a relay (whether its a 1 channel relay or an 8 channel relay) can be connect simultaneously to 4 seperate but identical solenoid switches that require 10.8-13.2 Volts to operate. They all must switch on and off simultaneously for my project which is why I'm curious if one channel would suffice.

I would be thinking about using a single MOSFET for about $1 US. Google "Arduino MOSFET" circuits to see what I am getting at.

The above is an example. You would parallel your solenoids.
