ATX423 - Temperature Measurement Module
ATX423 module provides monitoring of four external analog temperature sensors based on PT100 or PT1000 sensors. Measurement accuracy equals 1°C. 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 along with other PLC controller modules, matched to the customer needs. The construction of the 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.
