B&R X90AISG0.02-00
9 to 32 VDC 2 full-bridge strain gauge inputs Data output rate configurable from 2.5 Hz to 7.5 kHz Special operating modes (synchronous mode and multisampling) Configurable filter level This module is equipped with 2 inputs for evaluating full-bridge strain gauges and works with 4-wire and 6-wire strain gauge load cells. The concept applied by the module requires compensation in the measurement system. This compensation eliminates the absolute uncertainty in the measurement circuit, such as component tolerances, effective bridge voltage or zero offset. The measurement precision refers to the absolute (compensated) value, which will only change as a result of changes in the operating temperature. Communication to the mainboard is made possible via X2X Link.
