The Siemens LOGO! AM2 Analog Expansion Module (6ED1055-1MA00-0BA2) is designed to extend the analog signal processing capabilities of Siemens LOGO! 8 basic units. Powered by 12 V or 24 V DC, this compact expansion module enables accurate acquisition of analog measurement values in automation systems where voltage and current signals are required.
The module provides 2 analog input channels that support both voltage (0–10 V) and current (0–20 mA or 4–20 mA) input ranges. This flexibility allows direct connection of common field devices such as pressure sensors, flow transmitters, level sensors, and industrial signal converters without additional interface modules.
Designed for seamless integration with LOGO! 8 controllers, the LOGO! AM2 ensures reliable analog signal acquisition and stable operation in compact automation panels. Its DIN-rail mounting design supports efficient use of space and straightforward system expansion in both new installations and retrofit projects.
