750-491/000-001
1-channel analog input

1 channel analog input; Resistance bridges (load cells); 125 ms dialing time; Light greyThe I/O module allows direct connection of a resistance measuring bridge. The bridge voltage VD and the supply voltage Vref of the bridge are digitized with 16 bit resolution. Two input channels for the resistor bridge are available as two 16-bit values for further processing purposes. The measurement result can be calculated by the formula: Measured value = V D / V ref . Field and system levels are electrically isolated.
