There is voltage reversal and EMC pro-tection.Voltage dips are not buffered.The subassembly does not need a diagnostics LED and no diagnostics infor-mation of its own is sent on the SmartWire-DT network. A fault in the 24 Vsupply voltage is therefore ascertainable only via the missing voltage of thedownstream contactors.abc
