As some of you know, I am using a solenoid valve that needs different voltages to activate based on the duty cycle. Currently, it does not run at 100% duty cycle so I have the PLC output (24V) directly connected to the valve. But we plan to add a mode that would keep the valve at 100% duty cycle, the valve needs 12V for this. I plan to use a 12V power supply to make this work. A logic in the PLC will determine whether the valve should be at normal duty cycle (24V) or 100% duty cycle (12V).
To make this work, I plan to use a 24V output from the PLC (mode) to activate a relay. The relay will switch between either 12V or 24V. This switching may happen frequently so I plan to use a solid state relay. The relay should have atleast one NO and one NC contacts.
Will this wiring scheme work? Any comments? Also, I was probably looking at all wrong places, but I couldn't find a solid state relay for this yet. The valve is 10W. Can someone recommend a good and simple solid state relay??
