The current measurement modules from IRS enable high-precision monitoring of operating and quiescent current, especially for industrial applications such as the automotive sector.
The CMM modules in Eurocard format plug into a standard 19" rack. They can also be integrated as a standalone device with one or more channels, for example in a benchtop housing.
Thanks to DAkkS calibration including an adjustment option and their high reliability, the modules deliver very accurate long-term results.
Recalibration can be integrated simply and is maintenance-friendly.
All modules offered have two communication interfaces for configuration and data acquisition:
- CAN/ CAN FD
- Ethernet
Key facts
- Current measurement from 1 µA up to 190 A (depending on the module)
- Automatic, uninterrupted switching between measuring ranges
- Monitoring of min, max and average values over any time period
- Continuous measurement with sampling rates up to 125 kSa/s
- Integration into test environments via C# DLL or LabVIEW library
