New X20 modules for strain gauges

The X20 I/O series by B&R has been enhanced with two new analog input modules that can be used to digitalise signals from strain gauges: the X20AIA744 with 2 full-bridge strain gauge inputs and the X20AIB744 with 4 full-bridge strain gauge inputs. Up to 4 strain gauge channels can now be housed in a module just as thin as a single-channel unit. Users save both equipment costs and control cabinet space.

The X20AIA744 and X20AIB744 modules work with 4-wire strain gauge load cells. Compensation in the measurement system eliminates absolute uncertainty in the measurement circuit, such as component tolerances, effective bridge voltage or zero offset. The modules each have 24-bit converter resolution.
