The AD4USB measurement converter is a 4-input A/D converter that allows the user to measure 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 higher-level system in digital form. The AD4USB communicates via USB. Power is also supplied via USB.
The default range (0 – 10 V) can be changed from 2.5 V to 100 V, or the current input from 0 – 20 mA, 4 – 20 mA or different depending on your needs. If you need a range that is not listed here, please contact us.
Features of the USB a/D Converter
- Four analog inputs for voltage or current
- Each channel can have a different range (on request)
- Measurement range divided into 10,000 parts
- Measurement speed: twice per second for each channel
- Communication via USB
- Spinel and Modbus RTU (MODBUS documentation upon request).
- Measurement software for observation and recording is supplied as freeware
- The measurement is based on a single 16-bit multiplexed sigma-delta A/D converter
Communication protocols
