Introduction:
ISO 4-20mA-E Series Active Load Two-wire 4-20mA Current Loop Isolation Transmitter IC is a kind of two-wire active 4-20mA sensor signal isolation regulator. It can convert active 4-20mA current signal into isolated passive control signal. The loop powered 4-20mA circuit achieves the perfect match between the sensor signal acquisition and the active load of analog input interface. It effectively solve the power conflict problem between the active 4-20mA current signal acquisition and the power supply in interface of two-wire loop powered circuits.
