The AS-BDAU-202 model by Schneider Electric is an analog output device primarily intended for use within the Modicon 984 series. This device is structured with two channels, affording multiple output capabilities for complex control tasks. It operates within a voltage range of ±10 V and permits current outputs of ±20 mA, making it suitable for various applications.

This unit maintains a robust isolation rating of 700 V, safeguarding channel-to-channel and channel-to-bus connections from potential electrical interference. Configuration includes a single slot requirement, simplifying installation in modular setups.

The device is organized into two groups, with one point dedicated to each. Input impedance specifications indicate less than 500 Ω for currents of ±20 mA and more than 5 kΩ for voltages of ±10 V. It provides a data range extending from 0 to 4000 counts, accompanied by an 11-bit plus sign resolution.

Furthermore, the accuracy of the AS-BDAU-202 maintains within ±0.4% of the full range, delivering reliable outputs, while its output error margin stays within ±0.6% when temperatures range from 0 to 60°C. Each channel typically delivers a conversion speed of 1 millisecond, ensuring quick response times for real-time processing needs. Powering this unit requires 60 mA at 5 V from internal sources and an additional 150 mA at 24 Vdc for external operations, which supports flexibility in system design. Weighing merely 0.5 pounds (0.22 kilograms), this device presents an efficient footprint for applications requiring precise analog control.
