It's a programmable device, so the code which runs it could serve a safety critical function and some standards would then refer to UL1998 or perhaps IEC 61508-1. I don't think 60950 has yet taken that "leap".

If you introduce 1 fault, the RCD will maybe not function as intended, but still it safe in the 950 meaning. But the disable RCD function may give another problem ... -----Opprinnelig melding----- Fra: Amund Westin [mailto:am...@westin-emission.no] Sendt: 29. april 2016 13:48 Til: EMC-PSTC@LISTSERV.IEEE.ORG Emne: [PSES] Residual-Current Device I have been asked by a previous colleague: You build yourself a custom RCD module (Residual-Current Device) to be placed inside a EN6950-1 product. For detection, process, safety relay control, etc., you make use of a FPGA. Does the introduction of a FPGA make any special issues for an EN60950-1 approval?
