The 6ES7138-4DE00-0AB0: Power loss is 2 W typical, so no forced cooling needed in most cabinets. Reverse polarity and short-circuit protection on the 24 V supply are built in. Group error LED (SF red) and synchronization LED (SYN green) provide on-module diagnostics without scanning the bus.
30 mm, matching the standard ET 200SP form factor for one base unit slot.
