  • ENTRIES:Part Number GuideData SheetFAQ
  • This series of products use professional MCU and 24-bit high-precision AD for data acquisition, non-linear processing algorithms and isolated measurement of the various models of thermal resistance and thermocouple signals, The transmission output is standard DC signal of 0 ~ 20mA , 0 ~ 5V, 4 ~ 20mA or 1 ~ 5V, 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.
