DESCRIPTION:
ISO 4-20mA Loop Powered Isolator IC recieves 4-20mA/0-20mA signals and transmit them through a single chip. The ceramic hermetic hybrid package contains an electromagnetic coupled converter and current module.The very low input equivalent impendence allows an ultra-wide voltage input range, so that it is able to meet the requirements that no distortion in long-distance signal transmission under the circumstance without any external power. The internal ceramic PCB, resistance and new isolation technique allow the IC to withstand the 3KVDC insulated voltage and meets the industrial requirements like the extremely poor temperature, humidity and shaking conditions. These specifications make the ISO 4-20mA Current Loop Isolation Interface IC very easy to install in PCB.
