The IC integrates a set of multi-isolated DC/DC converter power supplies and a set of magneto-electric coupled analog signal isolation amplifiers on the same chip. It adopts a low-cost scheme of magneto-electric coupling and is mainly used in applications with no special requirements for EMC (electromagnetic interference). Wide creepage distances on the input and output sides and internal isolation measures enable the chip to achieve 3000VDC insulation voltage. 

      ISO EM-T series analog magnetic isolation amplifier transmitter internal electromagnetic isolation technology, compared with optocoupler isolation has better temperature drift characteristics and linearity. The zero point and gain of IC can be adjusted and calibrated by external multi-turn potentiometer, which is convenient for the industrial site to adjust and calibrate according to the working and running status of the instrument and equipment. The products are widely used in power operation safety monitoring, PLC, DCS, FCS, frequency converter, instrumentation, medical equipment, industrial automation and other industries that require power isolation collection, measurement and control.
