Hello RAJKIRAN, Just few words to add to the good reply of Daniel. Any 4-20mA will support both 2-wire connection and 4-wire connection but some modules (like the one you have) support the 2-wire connection but with external supply while some other modules support the 2-wire connection without external power supply. Best regards. H-H
