Siemens 6ED1055-1MB00-0BA2 Programmable Logic Controller

Siemens 6ED1055-1MB00-0BA2 is the LOGO! DM8 12/24R expansion module for the LOGO! 8 programmable logic controller. It adds four digital inputs and four relay outputs to a LOGO! 8 system, enabling expanded sensing and actuation without replacing the base unit. The DM8 module operates from a 12–24 V DC supply and features relay-type outputs capable of switching inductive loads up to 3 A, making it suitable for driving coils, small actuators, or relays directly from the LOGO! 8 network. It mounts on a standard 35 mm DIN rail and occupies two spacing units, aligning with Siemens' LOGO! 8 expansion configurations for compact panel installations. The part is cataloged as LOGO! expansion module DM8 12/24R (6ED1055-1MB00-0BA2) and is designed to pair specifically with LOGO! 8 controllers, offering scalable I/O as applications grow—ideal for small- to mid-sized automation tasks such as process sensing, simple sequencing, and control of relays or indicators within a DIN-rail mounted panel.
