Product Description
The 3AI775. 6 B&R Automation 2005 series is an analog input module intended for usage in various processes which is designed by the company. This module has 8 differential inputs and is appropriate for numerous applications across the industrial spectrum where analog measurements must be accurate. Ideally, each input can accept up to 0 to 20mA of current and is set to have upper and lower shutdown currents of -50mA and 50mA respectively.
It has a digital converter resolution of 12 bits, which means that the conversion of the signal is very accurate and the non-linearity is +/ - 1 LSB. The conversion procedure in the presented module relies on a successive approximation method, which enables a conversion time of less than 1 ms for all the channels in normal and special operating modes. These input signals are electrically isolated from the PLC making the module more reliable and safer. The 3AI775. 6 specifically fulfills the Performance Evaluation Discriminator of 85% and has an input filter composed of a low pass 1st order that assists in sound signal noise rejection the low pass being at a cut-off frequency of 450 Hz. It should also be noted that the module's basic accuracy is ~0. 1% at 25 degrees C, an offset drift of at most 0. 0025% per degrees C, and a gain drift of ~0. 01% per degrees C which makes the unit to be stable at different operation conditions. Also, it has a repeat precision of ~0. 05% and Crosstalk rejection between the channels is -66 dB which is of high impact.
The 3AI775. 6 is performed in cyclic measurement with the ability of averaging an optional result together with the direct software timing which is set to the default time from 2000 - 65535 us. It consumes a maximum of 4.5 W power, distributed as 1 W from the 5 V supply and 3.5 W from the 24 V supply. The voltage drop at a full load of 20 mA is 1 V, and it maintains a load resistance of 50. This module is classified as C-UL-US and is suitable for all applications that need accuracy in current measurement and stability in industrial settings. The product is available at Wake Industrial with a one-year warranty period.
