For a personal project, I need to be able to control a 9V/DC latch solenoid that will open and close a water valve that will be a part of a temperature controlled cooling system in a winery.
These are the specs of the solenoid (Bermad S-392-2W):
Voltage Range: 6-20 VDC Coil Resistance: 6 Ω Coil Inductance: 90 mH Pulse Width: 20-100 mSec. Required Capacitor: 4700µF
The advantage of a latch type solenoid is that it consumes power only when switching positions, using a very short electric impulse in either forward or reverse polarity to open and close it.
Being a noob, I don't really know how to implement this, i.e. how to interface the solenoid with the arduino, in the simplest possible way. A TIP120/102 is NOT an option as it doesn't address the need of reversing polarity. Would an H-bridge be an option? In that case, how should it be wired?
Also, where should the "required capacitor" be placed?
Any help would be greatly appreciated.
