all of my designs are based on sinking inputs and sourcing outputs.
for sinking inputs, power is applied to the sensor, the sensor then feeds the plc input which sinks the signal to the co common terminal. less power required with these types of inputs.
for outputs, the plc output module supplies power to the device and also requires less power.
I have never seen a Japanese design using sourcing inputs and sinking outputs, doesn't mean they don't. I just haven't seen one.
