This may sound like a stupid question but I feel like I should ask before giving up.
I have an older PLC which control a step conveyor. I want to add a few engines with an additional small PLC. The sensors installed are NPN which fit (I guess) the old one. The new PLC I got requires PNP input. Attached you can find a diagram for implementing NPN with a 10Kohm resistor.
Is there a way to do this with these two different PLCs? If not, just out curiosity, can I do it with two PLCs which both require NPN?
Thanks
