The difference between a 2 wire and a 4 wire is the power supply.A 4 wire has 2 wires for power supply and 2 for the control signal. A 2 wire is a 4/20ma transmitter that uses the leakage current thru the load to power the transmitter.IE a 2 wire prox, versus a 3 wire prox.he signal will of course always vary between 4 and 20mA, but not the power wires. The big difference is that a 2-wire transmitter have a higher minimum voltage drop (typically 10V) than the 4-wire transmitter. That means there are more voltage drop availiable for the wire.
