Product Technical Profile – ABB BAMU-11 (3AUA0000109935 / 3AUA0000109935-D)
1) Brand and Series Overview
Brand: ABB
Series: BAMU Series – Base Analog Measurement Units
The BAMU Series consists of modular analog measurement and signal conditioning units developed for industrial automation and drive systems. These modules are engineered to provide reliable analog input/output processing, signal isolation, and monitoring functions within control cabinets and automation panels.
The BAMU-11 model is positioned as a high-stability analog measurement module within the series, supporting precise signal acquisition and transmission for industrial control environments. The “-D” version typically indicates a minor hardware revision or design update while maintaining functional compatibility.
2) Product Overview
The ABB BAMU-11 (3AUA0000109935 / 3AUA0000109935-D) is an industrial analog measurement and interface module designed for accurate acquisition, isolation, and transmission of analog signals. It acts as a bridge between field-level instrumentation (such as pressure transmitters, flow meters, and temperature sensors) and higher-level automation systems including PLCs and distributed control systems.
This module ensures signal accuracy, electrical isolation, and operational stability in environments exposed to electrical noise, voltage fluctuations, and varying temperature conditions. Its compact DIN rail-compatible design enables efficient integration into existing control cabinets without significant structural modifications.
BAMU-11 is commonly used in industrial automation systems requiring dependable analog signal monitoring and control loop support.
