6ED1055-1MB00-0BA2 Siemens LOGO! DM8 12/24R Digital Expansion Module, 4 DI / 4 Relay Outputs
The Siemens 6ED1055-1MB00-0BA2 is the LOGO! DM8 12/24R, a digital expansion module for the LOGO! 8 logic module family. It adds 4 digital inputs and 4 relay outputs (5 A) to a LOGO! 8 base module, runs from a 12 V or 24 V DC supply and is only 2 spacing units wide on a 35 mm DIN rail. It is an easy way to expand the I/O of small automation tasks such as lighting, pumps, gates, HVAC and small machines when the base module’s I/O is no longer enough.
