2AT610.6
The B&R 2AT610.6 analog input module, part of the B&R System 2010, specializes in temperature measurement with thermocouples, supporting types L, J, and K with a measuring range of -200 to +1300°C. Featuring 16 differential inputs, this module suits industrial applications requiring precise temperature control. Organized into four groups of four channels, the module ensures safety with galvanic isolation from the PCC and other groups, enhancing noise immunity. It maintains a nominal input range of -15 to +55 mV and boasts a differential input resistance over 1 MOhm for accuracy. A Bessel low-pass filter with an 8 Hz cut-off reduces noise, providing stable readings in electrically dense areas. Its DC and AC common mode rejection ratios are 80 dB and 75 dB at 50 Hz, respectively. The module uses an integrated voltage-to-frequency converter with adjustable measurement times, offering an internal resolution exceeding 14 bits, or 0.1°C per bit.
