X20AT2222
The X20AT2222 by B&R Automation is a precision temperature input module from the X20 series designed for accurate temperature measurement using resistance. It supports PT100 and PT1000 sensors, known for their precision, allowing 2-wire or 3-wire connections per module to accommodate various configurations without compromising accuracy. Its 16-bit digital converter ensures high-resolution temperature data sampling at 0.1°C. The module internally linearizes temperature data according to the EN 60751 standard. It offers short conversion times, from 20 ms for a single channel with a 50 Hz filter to 80 ms for dual channels, along with adjustable filter times (1 ms to 66.7 ms) for optimal noise reduction and sensitivity. Operating temperatures range from -25 to +60°C horizontally and -25 to +50°C vertically, withstanding storage temperatures from -40 to 85°C. With low power consumption (0.01 W from the bus and 1.1 W internally) and an IP20 protection rating, it is both energy-efficient and durable.
