Hi all, I have Delta 12SA2 11T transistor type plc and I am confused about the output wiring, A video on youtube : https://www.youtube.com/watch?v=8kW9AwN2fs4 says that we can connect UP to +24V and ZP to 0V for sinking outputs (NPN wiring) figure1 and the reverse i.e., connect UP to 0V and ZP to +24V for sourcing outputs (PNP wiring) figure2, please see the img.png attached here with. (image link : https://drive.google.com/open?id=1idegjXoAQ-Vmu4zMeCWN1PPWUMB-WgaS)
The first one is working ok but the second one not, when i connect UP to 0V and ZP to +24V for sourcing outputs (PNP wiring) figure2 then my indicator remains always ON no mater i trigger the output on or off
The manual says that the PLC only has NPN transistors in the output inside the plc then how he in the video is showing both ways.
Please help me to understand this.
Thanks in advance.
