AS-BADU-214

Schneider Electric's AS-BADU-214 module is structured as an analog input unit, specifically designed for the Modicon TSX series. It supports four four-pole RTDs or eight two-pole voltage sensors for flexible input configurations. The module lacks electrical isolation, making implementation considerations relevant.

For voltage measurements, users can work with bipolar options of ±0.5, ±1, ±5, and ±10 VDC, or unipolar measurements ranging from 0 to 0.5, 0 to 1, 0 to 5, and 0 to 10 VDC. It has an input impedance of 1 Ω, ensuring minimal interference across voltage ranges. The voltage resolution stands at ±0.003% of the range value with a 15-bit resolution plus sign realization while the measurement error is ±0.02% MFV and ±0.11 mV for 5 and 10V configurations.

Current measurements can be bipolar or unipolar. Bipolar options include ±10 mA signaling (+0.5 V) and ±20 mA (+1 V). The unipolar choices are set for 0-10 mA (0-0.5 V) and 0-20 mA (0-1 V). Furthermore, current offset options of 2-10 mA and 4-20 mA are available, facilitating enhanced control over the input parameters.

The AS-BADU-214 is also capable of temperature measurement, particularly for Pt100 sensors, with a temperature range that spans from -160°C to +160°C and features a resolution of less than 0.02°C. The input impedance for temperature measurements exceeds 1 MΩ, promoting accuracy and reliability. Note that there is no conformal coating applied to this module. As an added safety feature, it incorporates over-voltage protection rated at ±30 VDC, ensuring operational integrity under varying supply conditions.
