ATX124 - Safety Circuit Module
Safety circuit module ATX124 was designed as intrinsically safe module. It provides monitoring of parametric safety circuit, which status reflects on status of output contacts of the module. The device provides SIL 4 degree of functional safety according to PN-EN 61508 norm in range of temperatures from 0 to 40°C and SIL 3 in range of temperatures from 0 to 70°C. Because of type of implemented intrinsically safe construction, there is version ATX124/12 (for supply voltage 9,5 to 13 V) and ATX124/15 (for supply voltage 12,5 to 15 V). 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 build in casing with at least IP54 protection degree and meeting the requirements of EN 60079-11:2012 norm.
