The Schneider Electric AS-BADU-206 module serves as an analog input interface that integrates with the Modicon 984 system. It encompasses four channels, each offering a two-pole configuration. The module ensures electrical isolation through an optically isolated bus, safeguarding sensitive components.

For functionality, it demands an external supply of 24 VDC, typically using between 60 mA and 100 mA. Versatile input voltage ranges are offered, accommodating bipolar variations of ±1 V and ±10 V and unipolar variations from 0 to 1 V or 0 to 10 V. It can also manage maximum voltage levels reaching +30 VDC.

The voltage input impedance exceeds 1 MΩ, allowing for minimal loading on the signal source. Current measurements are supported as well, offering bipolar input ranges of ±20 mA, with an upper limit of 40 mA. For current input, the impedance is measured at 50 ohms. The device boasts an 11-bit resolution for precise data capture.

It features rapid conversion times of under 10 milliseconds per channel, ensuring quick response for time-sensitive applications. Operating accuracy is maintained within ±0.4% for voltage and ±0.56% for current across a temperature spectrum from 0°C to 60°C, highlighting the module's reliability within specified environments.
