Product Description:

The X20AIA744 is an analogue input module designed by B & R Automation according to international standards. This module is a compact unit with about two full-bridge gauge inputs, and maintains a converter resolution of 24-bits during operation. The small, lightweight design of this product makes its installation relatively easy for well-trained personnel. Troubleshooting operation is also easy since the unit comes with diagnostic status indicators that signal any fault related to the operation of the product. The average power consumption of the bus unit in this product is estimated to be about 0.01 watts, its internal input/output unit also consumes about 0.7 watts of power. The X20AIA744 comes with several certification interfaces and markings; these include the ATEX, UKCA, CE, and the UL certification marking.

The X20AIA744 is an IP20 product that requires installation inside a control cabinet which meets a minimum protection category of about IP54. Temperatures where the unit is installed should also be controlled and maintained below 40 degrees. The full-bridge strain gauge design of this product operates with a 4-wire connection, and a differential input type. The conversion time at the strain gauge is estimated to be about 500 microseconds while its data output rate is about 5000 samples per second for every channel on the unit.

The X20AIA744 features an input filter with a cut-off frequency of approximately 2.5 kilohertz. The cables used with this product should be twisted and shielded conductors, the length should be as short as possible, and they should also be routed separately from load circuits. Operators are allowed to mount this unit in both horizontal and vertical orientations. Installation height for operation without derating should be between 0 and 2000 meters above sea level.
