Dual Loop Powered Isolated Signal Conditioner, Small Industrial 4-20ma Signal Isolator

ISO 4-20mA Current Loop Isolation Interface IC provides signal receive and transmittal on a single chip. The ceramic hermetic hybrid package contains an electromagnetic coupled converter and current modulate. The very low input equivalent impendence allows the input voltage can be
up to an ultra-wide range (7.5V~32V), so that it is able to meet the requirements for no distortion in long-distance signal transmission under the circumstance of no outside connecting power. The internal ceramic PCB, printed impendence and new isolation technologies allow the IC for the 3KVAC insulated voltage and meets the industrial level for the extremely poor temperature, humidity and shaking conditions.

Applications:

·PLC,DCS analog signal data acquisition and isolation ·Industrial process 4-20mA signal isolation ·Ground-loop elimination ·No distortion in long distance signal transmission ·Instrument signal acquisition ·Electric supervision , medical application and Isolated safe bar
