Siemens LOGO! DM8 24 Expansion Module 6ED1055-1CB00-0BA2

6ED1055-1CB00-0BA2 Overview

The LOGO! DM8 24 (6ED1055-1CB00-0BA2) is the transistor-output variant of the digital expansion modules for the Siemens LOGO! 8 logic platform. In place of relays, its 4 outputs are electronic transistor stages rated for 24 VDC at up to 0.3 A, which switch silently and without contact wear - an advantage on duties with high cycle counts, such as status lamps, small pneumatic valves, counters and interlock signals to other controllers. The 8 digital inputs accept 24 VDC sensors and switches. Like its relay siblings, the module clicks onto the LOGO! system bus, is configured together with the base unit in LOGO! Soft Comfort, and mounts on a 35 mm DIN rail in the compact family housing. It is a practical choice where LOGO! 8 systems need fast, quiet, low-current switching rather than power relay outputs.

Why Choose Siemens Logic Module Technology?

• Wear-free transistor outputs: 4 electronic outputs (24 VDC, 0.3 A) switch without mechanical wear.
• Integrated with LOGO! 8: System-bus expansion programmed in LOGO! Soft Comfort per Siemens documentation.
• High-cycle suitability: Electronic switching suits signaling duty with frequent state changes.
• Consistent family format: Same DIN-rail housing and configuration flow as the LOGO! 8 system.
