PLC 0-10v led driver not getting 0v

Postby Gowrilla » Mon May 06, 2019 2:52 pm

PLC : MDuino 42+ (isolated 0-10v analog output)
Led driver : Mean Well PWM-120-24 (dimming 0-10v)

Output PLC measures 0 to 10v perfectly when driver is not connected. But when connected the 0v is never reached, instead I measure 0.6v, and the ledstrip does not dim completely.
Anybody any ideas what's causing this? Thanks.
