Verified industrial suppliers (5GPLC, PLC DCS Pro) consistently identify it as a \u003cstrong\u003eRedundant SLS Controller Module\u003c\/strong\u003e for safety logic execution. A minority source describes it as a power supply module, and another (CSDN blog) lists analog output parameters that do not align with the SLS controller description.
