ISOH 4-20mA-E series module employed high-efficiency power stealing technology which makes the IC can operating without independent power supply. And the two-wire loop powered output method used which largely reduces the costs for customers in installation. Inside the IC, there are current signal modulation circuit and signal coupling power stealing and isolated conversion circuit,etc. Input very low equivalent resistance to acquired the extra-wide voltage value (5~32VDC) in the current signal from the loop of instrumentation and sensor or transmitter as working power for signal transmission and conversion, meets the needs of users to transmit distortion-free signal in long distance without power supply.
The output of ISO 4~20mA-E was designed for the two-wire powered loop of series connection between 24VDC and sampling resistors (two-wire instrumentation), it is matched with the analog input interface board (host machine), PLC, DCS or other instruments (With active load in analog input port) commonly used in industrial fields. The module achieves the isolation, transmission and acquisition of two-wire 4-20mA signal by add an external 2KΩ multi-turn potentiometer to do adjustment, and meets the requirements of harsh working environments with industrial grade wide temperature, humidity and vibration. SIP 16 Pin PCB mounted and DIN 35 Rail mounted packages are available, which were widely used in rail traffic voltage monitoring, power generator or electric motor safety operation monitoring, electric power transmission and distribution long distance monitoring, signal transmission and reception between instrument and meter, medical equipment isolation safety barrier, industrial intelligent control, nuclear power, etc. field.
