Product Description:
The X20ATA312 is a high-accuracy temperature and resistance measurement module, manufactured by B & R Automation. This module directly measures resistance and eliminates the necessity for extra signal conditioning hardware. This module has 2 × PT100 (4-wire) inputs through which accurate temperature measurement can be performed using standard RTD sensors.
This X20ATA312 module has a 24-bit digital converter that provides high-resolution capture of temperature and resistance inputs. Its sigma-delta conversion process ensures accurate signal conversion with minimal noise for use in applications requiring stable sensor feedback. The temperature measuring range of this module is between -200°C and 850°C, and it can accommodate a diverse set of industrial temperature-sensing applications. In resistance mode, the measuring range of this module extends from 0.5 to 390 Ω, which covers the majority of RTD sensors and special resistance-based transducers. To adjust signal integrity and process control flexibility, the filter time of this module is adjustable between 1 and 200 ms so that the customer can fine-tune the response rate as per the needs of the application. With IP20 protection according to EN 60529, this module is designed to be installed inside control cabinets or shielded enclosures.
The sensor resolution of this module is set to 1 LSB = 0.01°C, providing high granularity of measurement, which is critical for accurate thermal control. The measurement output of this module is available in either DINT or UDINT format to ensure compatibility with a broad spectrum of PLC and control systems. In terms of efficiency, the bus power consumption is only 0.01 W to make the X20ATA312 a low-consumption solution for real-time monitoring conditions. This module can be installed at elevations of between 0 and 2000 m above sea level to ensure functional stability in different physical environments.
