Current Loop Converters

Our Current Loop Converters use current on or current off to transmit binary digits. B&B current loop converters interface RS-232 and RS-422/485 systems to the most common current loop ports, 20 mA ports with open circuit voltages up to 30 V. Many models can be modified for higher loop currents and voltages.
