DESCRIPTION&colon;

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