BECKHOFF KL3351 1-CHANNEL RESISTOR BRIDGE INPUT TERMINAL, 16 BIT
Quick Overview
Manufactured By: BECKHOFF
Manufacturer Part Number: KL3351
IMS Product Code: 1759041
Packaging: Sold Individually
Description:
Beckhoff KL3351 Bus Terminal, 1-channel analog input, measuring bridge, full bridge, 16 bit
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.
