Two-Wrie 4 to 20mA Current Loop Isolator IC (ISO 4-20ma)
CHARACTERISTICS:
· Low cost, small size, standard SIP12 package
· Electromagnetic Isolation
· Signal input/output, 3000VDC isolated voltage
· No external instrument needed for power supply
· 4-20mA high accuracy of current input/output(distortion<0.2%)
· Industrial temperature(-45~+85 º C)
· High linearity(Nonlinearity<0.2%)
· Small signal bandwidth: 50HZ
· Weld to PCB directly
APPLICATIONS:
· Analog signal data acquisition and isolation
· Isolated 4-20mA signal transmission
· Industrial process signal isolation
· Ground-loop elimination
· No distortion in long distance signal transmission
· Instrument signal acquisition
· Electric supervision and medical application
· Isolated safe bar
· Biomedical measurements
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.
