Hi there,
I have a 2 wire npn sensor. For example in this diagram:
I'm guessing i should connect it to a PLC dc sourcing input as such? Would i need a resistor between the PLC #1 DI to the sensor Collector ?

ow can i just have the brown wire of the sensor goes to input 1, and black wire goes to common (0 Vdc)? Assuming the PLC sourcing digital input internally already has a resistor?
I always used a 3 wire npn sensor, and wiring is done as such:
