4 - 20mA

16-bit 4 to 20mA analog output corresponding to weight is provided in the form of linear current to drive PLC controllers for process control applications. Long distance transmission of weight data without any deterioration of signal can also be achieved by using analog output. Relay indication provided to show availability of 4-20 mA current output.
