The supply voltage Uv can be
drawn from the terminal or
can be supplied from an
external source. The terminal
supplies 5 V. The maximum
input voltage UREF is limited
to 10 V.

Precise strain measurement in the I/O system

Precise strain measurement in the I/O system

The KL3351 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 16 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 16 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.
