1AI DMS 750-491

Product description:

The analog input module enables the direct connection of a resistor measurement bridge. The brigde voltage UD and supply voltage Uref of the brigde are digitised with a resolution of 16 bits. The input channels for the resistor bridge are available as two 16 bit values for further processing. The result of measurment can be calculated by the formula: Measured value = UD/Uref . Due to the accurate measurement of supply voltage as well as bridge voltage in one measurement transformer, long-term and temperature drift are compensated. Field and system level are electrically isolated. All I/O modules are independent of the fieldbus and automatically connected to the next module when snapped onto the DIN rail. To improve the electromagnetic compatibility (EMC) ground (earth) the DIN rail.
