EL3351 | EtherCAT Terminal, 1-channel analog input, measuring bridge, fullВ bridge, 16В bit

The EL3351 analog input terminal permits direct connection of a resistor bridge. The bridge voltage, UD, and the supply voltage, UREF, to the bridge are digitized with a 16В bit resolution, and are transmitted along an electrically isolated channel to the supervising automation system. The input channels are available in the form of two 16В bit values for further processing. The resulting measurement can be calculated from the formula: measurement = UD/UREF. Precise acquisition of the supply voltage along with the bridge voltage compensates for long-term and temperature drift.
