Siemens 6ED1055-1MA00-0BA2 LOGO Expansion Module

Siemens 6ED1055-1MA00-0BA2 LOGO AM2 expansion module adds two analog input channels to a LOGO! controller, enabling direct reading of analog sensors without a separate interface. It is powered from a 12/24 V DC supply and is designed to extend a LOGO! installation with additional sensing capability. The two AI inputs (AI1 and AI2) can be configured for voltage signals in the 0–10 V range or for current signals in the 0/4–20 mA range, allowing direct connection of common analog sensors such as temperature probes or process transducers with standard outputs. The module communicates with the LOGO! CPU via the built-in expansion interface and shares the same power domain, delivering a compact, plug‑in method to broaden analog measurement options in simple automation tasks. This part is specifically described as the AM2 expansion module for LOGO!, providing two analog inputs to support monitoring and control of analogue signals within a LOGO! system.
