Siemens LOGO! DM8 230R Expansion Module 6ED1055-1FB00-0BA2

6ED1055-1FB00-0BA2 Overview

The LOGO! DM8 230R (6ED1055-1FB00-0BA2) is a digital expansion module for the Siemens LOGO! 8 logic module family, the compact controller platform documented by Siemens for small automation tasks. This variant adds 8 digital inputs rated for 230 VAC - practical where pushbuttons, float switches and contactor feedback arrive at line voltage - and 4 relay outputs with 10 A switching capacity, able to drive contactors and valve coils directly. The module clicks onto the LOGO! system bus and appears in LOGO! Soft Comfort like the base unit's own I/O, so existing programs can simply be remapped. With a 35 mm DIN-rail mount and the compact LOGO! housing width, it fits the same control cabinet footprint as the rest of the family. As an expansion part for installed LOGO! 8 systems, it is a common item in building control, pump stations, gate and lighting controls and similar small-machine applications.
