Our sales group is quoting a project where an engineering firm has listed out that the safety circuit be powered from a SIL-certified 24VDC power supply. I've gone through the few different brands we typically use for our power supplies (AB, Carlo Gavazzi, Sola) and have found the units have various CE, EN, and UL approvals but no mention of any SIL-level capabilities in their datasheets. Haven't had much luck searching online for a power supply model that lists out a SIL level.
Anyone come across this or aware of a brand that expressly lists a SIL-level for the power supply? Otherwise, IEC 61508 is what defines SIL levels, but that's not an approval I see any power supplies to have.
Thanks in advance.
