AD4USB measuring converter is a 4-input A/D converter which enables the user to measure to four current inputs ranging from 0(4) to 20 mA or voltage between 0 and 10 V. The measured values are then transferred to a superior system in digital form. The AD4USB communicates via USB. Powered is also via USB.

Default range (0 - 10V) can be changed from 2,5V to 100V, or current input 0 - 20mA, 4 - 20mA or different depending on what you need. If you need a rande that is not listed here, please contact us or write the desired range in the note below while ordering.Introduction to measurement converters AD4 series.

Features of USB A/D converter

  • Four analogue inputs for voltage or current
  • Each channel can have different range (upon request)
  • Measuring range split into 10 000 pieces
