2wire Sensor Diagram For Plc. Wiring diagram for npn and pnp 4 wire sensors d2 16nd3 2. The output operation is along the two power wires in the form of a voltage drop thus making the sensor free to work with either polarity on the common.
Connect 3 wire npn proximity sensor to s7 200 plc. 2 wire transmitter current loop diagram. The receiver itself could be any number of different devices such as.
The load is a device that is being controlled by the sensor.
The power wires will connect to a power supply and the remaining wire to some type of load. Connecting a 4 wire dc sensor is the same as a 3 wire sensor but each output wire is connected to a different input on the input card. If the plc is in a panel and you cannot see the actual inputs and outputs io there is. 2wire sensor diagram for plc.
