ISO photoelectric isolation amplifier transmitter series is a hybrid integrated circuit which will be amplified and converted into a proportional output analog signal by the DC signal isolation and amplification. The IC is integrated with a plurality of isolated DC/DC converter power supply and a set of photoelectric coupling analog signal isolation circuit, input and output side wide range of the input voltage and internal isolation measures to enable the chip to achieve signal input / output / auxiliary power supply 3KVDC three insulation voltage. Easy to use, no external components to achieve the signal current source long-term transmission. The object and data acquisition system are isolated, which can improve the common mode rejection ratio, and protect the electronic instrument equipment and personal safety.
ISO series analog optical amplifier transmitter with a low cost solution of linear opto electronic coupling, which is mainly used for EMC (electromagnetic interference) has special requirements. The DC analog signal photoelectric coupling transmission technology, and the simulation is not ISOEM series volume magnetic isolation transmitter products used in the signal modulation and demodulation carrier technology, so photoelectric isolation than the electromagnetic isolation type has strong anti EMC electromagnetic interference and high frequency signal space interference characteristics. The zero point and the gain of IC can be adjusted by the external multi circle potentiometer, which can adjust and correct the operation status of the industrial field. Products are widely used in electric power operation safety monitoring, DCS, PLC, FCS, frequency converter, remote monitoring, instrumentation, medical equipment, industrial power automation and other need to isolate and measure the power of the industry.
ISO products are: PCB board welding module and DIN rail card slot fixed two installation method. ISO series products are all isolated type, auxiliary power supply is also isolated, so it is necessary to separate power supply. Input power can not be shared with the auxiliary power supply, input, power, output, the three ground to allow any two, please note.
