Product Description:

The 3AI350.6 is a robust analog input module from B&R Automation designed for precise voltage measurement in industrial environments. This module comprises eight differential input channels that can take a nominal input voltage of -10V to +10V with an input range limit of -20V to +20V.

It also comes with a 12-bit digital converter with a non-linearity of ~1 LSB to make data acquisition as accurate as possible. It uses a successive approximation method for the conversion procedure; however, it offers a quick conversion time of less than 1 ms for all channels in normal and special operating modes. The signals feeding the module are electrically isolated from the PLC, which improves its performance in industrial applications. This module contains an input filter with a low pass first order, it has a cutoff frequency of 450Hz to reduce the noise level of the signal. It has a typical accuracy of ~0. 1% at 25 degrees C, which has an offset drift of a maximum of ~0. 0037% per degrees C and gain drift of ~0.0075% per degrees C. The repeat precision is ~0.025%, and it provides impressive cross-talk rejection between channels at -66 dB. It works in different modes: the cyclic measurement with the averaging (from 1 up to 255) in option and direct software timing with setting the default time from 2000 to 65535 us. It takes a maximum of 4. 5 W power, divided into 1 W from the 5 V supply, and 3. 5W from the 24 V supply.

The module has dimensions of the B&R 2005 single-width standards, thus easily fitting in existing systems. By being C-UL-US listed, the 3AI350 is. 6 is recommended for use in situations where accurate measurements of voltage are needed and when dependable performance in harsh industrial environments is expected. The product is available at Wake Industrial with a one-year warranty period.
