AS-BADU-205

The Schneider Electric AS-BADU-205 module serves as an analog input device within the Modicon 984 series. This module supports a total of four two-pole analog inputs, ideal for various measurement applications. The allowable input voltage range is bipolar, rated at ±10 VDC and allowing maximum values up to ±19.99 VDC. For current inputs, it accommodates a rating of ±20 mA, reaching maximum peaks of ±39.95 mA.

Input impedance characteristics reveal a voltage impedance of 50 kΩ, while the current input impedance stands at 50 Ω under a rated condition of ±20 mA. In terms of performance specifications, the AS-BADU-205 ensures high operational precision, delivering A/D conversion with a 12-bit resolution that also accounts for sign.

Conversion times for this module are less than 80 milliseconds at 50 Hz, while at 60 Hz, the response time is reduced to below 66 milliseconds for each input channel. It operates effectively across a temperature range of 0 to 60°C with an operating error limit maintained at just 0.5% of the input value. Note that there is no electrical isolation in this module, and it demands an external bus power supply of less than 50 mA. The maximum input voltage can reach ±30 VDC and can handle input currents up to ±44 mA without compromising accuracy.
