This analog input module directly connects to two resistor bridges.<br/>The bridge voltage U<sub>D</sub> and supply voltage U<sub>ref</sub> of the respective bridge are digitized with a resolution of 16 bits.<br/><br/>The two input channels for the respective resistor bridge are available as two 16-bit values for additional processing.<br/>The bridge detuning can be determined from the quotients of the two measurement values U<sub>d</sub> and U<sub>ref</sub>.<br/>Functional galvanic isolation is provided between both channels.<br/>The internal supply voltage is derived from the system supply.<br/>The supply of a separate 24 V field voltage is not necessary. The voltage supplied via the power jumper contacts is looped through to downstream I/O modules.<br/>The shield connects to the DIN-rail.<br/>The module is parameterized via GSD file, <b><i>e!</i></b><i>COCKPIT</i> or WAGO-I/O-<i>CHECK</i>.
