WBT1C1CS03 is a standard two-wire DC current conditioner. It uses the principle of photoelectric isolation to convert 4mA~20mA DC signals into 4mA~20mA DC signals. Input and output are isolated. It has the advantages of high isolation, high accuracy, low drift and wide temperature range. This product is mainly used to suppress strong electrical interference and common mode interference during the transmission of sensors and meters. It is especially suitable for use with sensors/transmitters and meters that require electrical isolation. This product can be widely used in computer, PLC and other measurement and control systems and automatic control fields.
