Description
This module enables the direct connection of a resistor measurement bridge. The bridge voltage UD and supply voltage Uref of the bridge are digitized with a resolution of 16 bits.The two input channels for the resistor bridge are available as two 16-bit values for additional processing. The result of measurement can be calculated by the formula: Measured value = UD / Uref. Field and system levels are electrically isolated.
