Hi folks,
I'm looking for some help to built a simple circuit which will output 2 separate analog voltages based on input PWM states (High/Low). As an example, I would like to output 20VDC when the PWM signal is high and 5VDC when the PWM signal is low. The PWM input will come from Arduino and there will be an external power supply to provide 24 VDC to the driver circuit.
It would be nice to have 2 pots to dial in the 2 different voltages. The PWM time base will need to be very slow (2 - 4 hz).
This driver is for a proportional solenoid valve (Asco 8202 series).
Some specs for the solenoid valve:
24VDC Valve
Flow is controlled by applying straight voltage from 0VDC to 24 VDC
Operating Current: 100 - 500 mA
Coil Resistance: 25 Ohm
Any help with the components required and circuit diagram would be greatly appreciated!
