Just put together the kit. Everything’s working fine I think. I’ve got 15v DC connected to 12…15V in. LEDs on Receiver PCB light up when switching 1 to 10 on Sender PCB. The only thing is I’m not getting any activity on 1 to 10 on receiver PCB. What values should i be getting there? Am I doing something wrong? I understand that I don’t have to have any other power supply if I’ve got DC connected to 12…15V in on receiver PCB.
I’m planing to use this kit with the relay kit to control a Sub Arc Welder.
Thanks
The outputs are open collector outputs, so it is normal that you do not measure any voltage.
