One Input Four Output Signal Isolator

This series of Signal Isolator use professional MCU and 24-bit high-precision AD for data acquisition, Measuring the DC input signal, while isolated output four-way standard DC signal of 0 ~ 20mA or 0 ~ 5V or 4 ~ 20mA or 1 ~ 5V. It is with high precision, high isolation, low power consumption, low drift, wide temperature range, strong anti-interference ability and so on. The transducer uses a fully isolated design, that is, input, output and power are isolated from each other, eliminating the mutual interference between the signals. This product is widely used in electric power, communication, railway, mining, metallurgy, transportation, instrumentation and other industries because of its ultra-thin housing DIN rail card-mounted structure, plug-in terminal wiring, installation and maintenance convenience.

  • It can switch the analog signal output to 0-20mA (0-5V) or 4-20mA (1-5V) output through the internal DIP switch. The four-way output signals are independent of each other.;
  • The internal is used digital adjustment, no potentiometer adjustment technology, the advantages of using the technical: product debugging convenience and product output has no influence from external mechanical vibration, product performance and stability.
  • The use of advanced digital-analog conversion circuit for DA conversion with stability output, low temperature drift.
