Bruker en G540 kontroller på fresen. Har en 12v solenoid jeg ønsker å styre via Mach3 (for kjølevæske og luft). Legger ved en skisse. Vil dette funke?

Pin 5 - Output
Pin 12 - PSU Ground

Hi Henrikm

your wiring diagram looks OK provided your valve take less than 1 Amp ( check the coil resistance is more than 12 ohms )

if your valve is like this valve you will have no problem :-

Buy Solenoid Valves Hydraelectric Solenoid Valve 72004, 2 port , NC, 240 V ac, 1/2in Hydraelectric 72004 online from RS for next day delivery.

( this valve requires 4W at 12v ---- the current taken = 4/12 = 0.3333A ---- the coil resistance = 12/0.3333 = 36 ohms )

Thanks John. My valve is actually 3W, so I should be good to go.
