I’m looking into using the Panasonic HG-C1100L3-P sensor as a much more precise alternative to the Keyence LR-X series. My PLC needs the I/O link capability of this particular HG-C model, but is currently set up to accept NPN signals; this I/O link-compatible HG-C only comes in PNP configuration, so it’s incompatible as things stand.
It’s my understanding that the PLC can be reprogrammed to look for the opposite signal, thus accepting the PNP signal, but that it may be designed for NPN with failsafe conditions in mind. Can anyone recommend any method of converting PNP to NPN, maybe via transistor or similar component integration? Any suggestions are appreciated!
