ABB SC520 3BSE003816R1 is a magnetically isolated hybrid IC, which integrates a multi-isolated DC/DC converter power supply and a set of magnetically coupled analog signal isolation amplifiers on the same chip. It adopts a low-cost solution of magneto-electric coupling, and is mainly used in occasions where there are no special requirements for EMC (electromagnetic interference). The wide creepage distances on the input and output sides and the internal isolation measures enable the chip to reach 3KVDC insulation voltage. ISO EM series products are very easy to use, free of zero and gain adjustments, without external adjusting potentiometer, can realize the isolation and conversion function of 0-±10V/0-±20mA bi-directional DC signals in the industrial field.

ABB SC520 3BSE003816R1 internal through the DSP, PLC DA conversion output signal to display and control other devices adjustable output, industrial site operating voltage, current and a variety of operating parameters of the monitoring and system external. Module is a kind of (sensor output) single analog voltage or current signal by isolation, distribution, converted into multiple precision, linearity matching the standard analog signal hybrid integrated module. The module internal integration of a number of ISO EM series of highly isolated analog signal isolation amplifier IC, the use of magneto-electric coupling of low-cost solutions, mainly for the EMC (electromagnetic interference) no special requirements of the occasion.
