I have 3 wire latch solenoid valves (2 valves) that I want to control from Arduino. from the datasheet, the valves require 15-24 VDC pulse (latch) depending on the condenser. Resistance: 3.5-14Ω Required length of pulse: 20-100 milliseconds. (https://galconc.com/wp-content/uploads/2014/12/B762-01.pdf)
Can someone help me to figure out the wiring scheme?
I did not find a complete answer to sketch for 3 wire valves.
As far as I understand it first wire is a ground, a second wire is for the opening pulse and the third for the closing pulse.
