The Siemens 6ED1055-1MA00-0BA2 is a LOGO! AM2 analog expansion module designed for the LOGO! 8 logic module family. It adds two analog inputs to the base unit, each configurable for 0-10 V or 0/4-20 mA signals, making it the go-to expansion for reading sensors, transducers, or analog setpoints in a small control scheme. The module accepts a supply range of 10.8 V DC to 28.8 V DC, covering both nominal 12 V DC and 24 V DC rails without needing a separate power supply. Typical current draw is 30 mA from the backplane.
The IP20 enclosure is suited for clean, dry control cabinets — not for wet or dusty field locations. Dimensions are 90 mm high by 58 mm deep, so it stays within the LOGO! footprint. Rated for ambient operation from 0 °C to 55 °C; firmware version ES03 and higher extends the lower limit to -20 °C. If the panel sees freezing temperatures, confirm the base unit firmware revision before committing the BOM line.
The module is specified into the BOM; confirm fit with the base LOGO! 8 unit and the analog sensor loop draw (the module itself draws 30 mA from the backplane).
Certifications and compliance
Carries CE, UL, CSA, FM, and marine approvals, plus VDE 0631 compliance. Developed per IEC 61131 and classified as limit class B for residential EMI — so it's fine for light industrial or commercial environments without additional filtering.
