Product Description

The X20AT4222 module from B&R Automation is a flexible yet effective temperature measurement unit that features four channels that are optimized for use with PT100 and PT1000 resistance thermometers. This module is also capable of providing high accuracy with a resolution of 0. 1 degrees C, which enables accurate temperature control in a wide variety of industries.

The X20AT4222 is versatile in terms of sensor flexibility given that it accepts 2-wire and 3-wire connections ensuring that the sensors are installed in a way that best fits the application while also offering accurate measurements. The input signal range for both PT100 and PT1000 sensors is from 200 to 850 degrees C thus suitable for most temperature conditions from cryogenic to high temperature processes. Energy requirements are low with the module, drawing power of 0. 01 W from the bus and 1. 1 W internally for I/O operations, which makes it an energy-efficient option for constant temperature measurement. The operating temperature is from -25 degrees C to 60 degrees C when the unit is mounted horizontally and from -25 degrees C to 50 degrees C when mounted vertically, making it suitable for installation in different conditions. The X20AT4222 also has a physically strong construction with a vibration level of 4g which is suitable for the tough industrial environment. It has an IP20 rating, which ensures that the module is protected against foreign objects but is not waterproof and should not be installed outdoors.

The other safety feature is the isolation voltage and the device has 500 V between the channels thus making each channel independent of the other and the bus to reduce the risks of electrical interferences. The conversion times are suitable for multi-channel systems; it converts a single channel in 20 ms while for two to four channels it takes 40 ms per channel thus ensuring the module can provide data in good time without much latency. The product is available at Wake Industrial with a one-year warranty period.
