ATX445 - LED Display Module

ATX445 module provides displaying four 2-digits numbers on 7-segments LED display organised as 4 lines 2 digits each. 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 od 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 providing at least IP54 protection degree and meeting the requirements of EN 60079-11:2012 norm.
