AS-BDAU-204

The Schneider Electric AS-BDAU-204 module operates as an analog output device with four independent channels. It can handle a variety of voltage outputs, including bipolar options of ±1 V, ±5 V, and ±10 V, as well as unipolar outputs ranging from 0–1 V to 0–10 V. Current output capabilities include both 0–20 mA and 4–20 mA, offering flexibility for various signal processing needs.

This module guarantees robust performance with at least 500 Vdc isolation between channels and the bus, which enhances reliability. Splitting functionalities into two groups allows for configuring two points per group, accommodating efficient management of your processes. Signal integrity is assured with a low current input impedance of less than 500 Ω and a high voltage input impedance exceeding 5000 Ω.

The system’s 12-bit resolution provides a clear and precise output measurement. Technically, it displays results in an unsigned 12-bit format, which numerically ranges from 0 to 4095. Performance accuracy is maintained at ±0.2% of full scale when operating at 25°C, alongside a linearity specification of ±1 LSB. The conversion time of fewer than 5 milliseconds per channel enables rapid data updates, which is essential for dynamic environments.

The AS-BDAU-204 includes fault detection for open circuits in current mode, ensuring immediate identification of operational issues. Power consumption is minimal, drawing less than 1 mA internally, while external requirements necessitate 200 mA at 24 Vdc. This makes the module highly efficient in energy usage for system operations.
