Nov 13, 2019· What this means is that PLCs will read HIGH at the input side only when the voltage is at 24 Volts DC. These discrete sensors have internal switching circuits that classify them as either a sinking (NPN) or a sourcing device (PNP). Basically, PNP provides +24 V as input, and NPN provides 24V as input.
