Spare-part designation and I/O count
The Siemens 6ED1055-1CB10-0BA0 is the spare-part version of the LOGO! DM16 24 expansion module, carrying 8 digital inputs and 8 digital transistor outputs in a single 4-width-unit (72 mm) housing. The 8 inputs accept 24 V DC nominal (permissible range 20.4 V to 28.8 V DC) with a signal-1 threshold above 12 V DC and a signal-0 threshold below 5 V DC, drawing 1.5 mA typical per input at signal 1. Each of the 8 transistor outputs switches up to 0.3 A at 24 V DC, with a maximum switching frequency of 10 Hz for resistive loads and 0.5 Hz for inductive loads.
Mounting and integration with LOGO! base modules
Depth is 53 mm, height 90 mm — the same envelope as other LOGO! DM series modules, so it fits existing enclosures without re-spacing.
No stock-holding claim is made here.
The module carries CE, UL, CSA, FM, and marine approvals, making it acceptable for installations in North America, Europe, and marine environments such as shipboard automation. It is developed in accordance with IEC 61131 and complies with VDE 0631, with limit class B for residential-area use.
