Differential Current Sensor with Analog Output

The DI-10S-A is a differential current Sensor for safety critical application, offering two independent analog outputs for full redundancy. Thanks to the non-intrusive clamp-on design, the sensor can be easily installed without requiring any disconnection, which makes it ideal for retrofit installations in industrial, IoT and metering applications. Furthermore, a broad dynamic range of currents can be measured and no calibration is required by the customer.


Supplied with a DC voltage of 5V or 10V, the module provides a linear analog output voltage between 0.5V and 4.5V or 1V to 9V as a function of the primary input current. Thanks to its properties, DI-10S-A offers an excellent linearity error, below 0.5 %FS. Thanks to the integrated Melexis IMC-Hall® current sensor, the sensor module provides excellent offset as low as ±5m̃V and sensitivity drift of 1 % over full temperature range.

The module has a differential output. Each Hall-Sensor will generate a rising or falling signal, depending on cur- rent the flow.
