PLC: Sensors and I/O Series--Digital Sensors
Part 2 of the Sensors and I/O Series displays general information on different digital sensors.
Show different digital sensors
Sensor needs some power to operate either dc or ac to perform its sensing
Explain they act the same as a switch
Maybe show DC sensor with relay.
Explain current levels and voltages
Different types of cords, quick disconnect, plastic, stainless, NEMA 4X For wash down
