ATX441 - Precise Temperature Measurement Module
ATX441 module provides monitoring of two external 4-wires temperature sensors based on PT100 or PT1000 sensors. Accuracy of measurement equals 0,1°C. The module can be equipped with one of three available interfaces: I2C, RS485 or CAN. The module has independent certificate from certification body that confirms meeting the requirements of ATEX Directive, what allows the module to be used in any hardware configuration. The construction of module meets the requirements of IEC61131 norm in range of standarization of functional and operational features and programming process. To keep appropriate intrinsically safe feature the module should be placed in a casing with at least IP54 protection degree and meeting the requirements of EN 60079- 11:2012 norm.
