Analog output not getting 0V

Situation :  Mean Well PWM-120-24 led driver (supports 0-10v dimming) connected to M-Duino 42+ analog output A0.5 and GND. Switch set to A0.5.

Problem : analogWrite(A0_5, 0) gives 0.6v instead of 0v. Decoupling the driver results in the correct 0v on the A0.5 pin. 

Question : Why 0.6V when the driver is connected?

Hello Filip,

Maybe is problem of the drive because our devices are well tested and work corectly. To get more information about the 42+ analog have a look here.

Thank you.
