  • ​ENTRIES:Part Number GuideData SheetFAQ
  • This series of products use professional MCU and 24-bit high-precision AD for data acquisition. It measures DC input signal, output with four-way standard DC signal of 0 ~ 20mA (4~20mA) or 0 ~ 5V (1 ~ 5V). With characteristics of high precision, high isolation, low power consumption, low temperature drift, strong anti-interference ability, the transducer adopts a fully isolation design,the input, output (four outputs are isolated from each other)and power supply are isolated from each other. This product adopts ultra-thin housing DIN rail card-mounted structure, plug-in terminal wiring, installation and maintenance are convenience, this product is intelligent design,with a variety of functions that are not available in traditional products, it is available to match with various instruments, DCS and PLC.

    * 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.
