Npn-PNP

[richerdick]

I have a sensor theat it an npn type output
i want to connect it to a plc that uses pnp inputs. i was thinking of using a solid state relay to convert the signal as it is quite a high speed applicaation can you forsee any problems

I would consider a rather strong pull-up instead. The logic needs to be inverted, but it is a simple solution.
