DM8 24 expansion module, 6ED1055-1CB00-0BA0, spare part, 4 DI / 4 DO transistor, 24 V DC, 2 DU wide, IP20.","salesMarkdown":"The Siemens 6ED1055-1CB00-0BA0 is a LOGO! DM8 24 expansion module — a spare part carrying 4 digital inputs and 4 digital transistor outputs, all running on 24 V DC supply. Each output switches up to 0.3 A rated for signal \"1\", with a maximum switching frequency of 10 Hz on resistive loads and 0.5 Hz on inductive loads — the inductive limit is the one that governs real solenoid or contactor drive. Supply tolerance spans 20.4 V to 28.8 V DC, so it holds steady on a lightly loaded 24 V bus or a floating battery-backed rail. ## Panel fit and approvals Depth is 55 mm, height 90 mm — a compact footprint that slides into a populated rail without rearranging adjacent blocks. Rated IP20, so it is intended for enclosure interiors only. Carries CE, UL, CSA, FM, and marine approvals — suitable for industrial control panels, building automation cabinets, and shipboard installations that require third-party listing. Developed in accordance with IEC 61131 and VDE 0631, with limit class B for residential-area use — the EMC emission level that lets it run in mixed-use facilities without extra filtering.","metaTitle":"Siemens 6ED1055-1CB00-0BA0 LOGO!
