Siemens LOGO! DM8 24R Expansion Module 6ED1055-1HB00-0BA2

6ED1055-1HB00-0BA2 Overview

The LOGO! DM8 24R (6ED1055-1HB00-0BA2) is the 24 VDC input variant of the digital expansion modules for the Siemens LOGO! 8 logic module platform. It adds 8 digital inputs for 24 VDC sensors and switches - the common voltage level for proximity switches, photoelectric sensors and pushbuttons in modern cabinets - plus 4 relay outputs with 10 A switching capacity for contactors, valves and similar loads. The module clicks onto the LOGO! system bus, inherits its supply from the base unit arrangement per documentation, and appears in LOGO! Soft Comfort as additional I/O of the same system. The 35 mm DIN-rail housing matches the LOGO! family footprint. Typical duty includes extending building automation, conveyor interlocks, pump controls and small machine logic where 24 V sensing meets relay-level power switching.

Why Choose Siemens Logic Module Technology?

• Integrated with LOGO! 8: The DM8 24R extends the LOGO! 8 platform and is programmed in LOGO! Soft Comfort per Siemens documentation.
