Hi Eastern, Which hardware you can use is determined by the level of risk. Generally speaking the FRO can achieve Category 4 when connected to a CAT4FDO. You need to monitor the NC contact using the F_FeedBack block from distributed safety. Other alternatives are the 3TK2830 or one/two Sirius 3RH12 or 3RT10 SUVA certified relays and contactors [number depends on category]. If you need the SIL/PL thenyou canuse the SET to calculate these values. But you must enter some values into the tool such as DC, number of cycles, etc [see the attached getting started]. Thereare examples found within the library folder of the tool to help you as well. AttachmentGettingStarted_en.pdf (831 Downloads) |
