B&R 3AM055.6 Analog Mixed Module

The 3AM055.6 is a high-performance analog mixed module from the B&R SYSTEM 2005 series, designed for integrated analog signal acquisition and control in industrial automation. It integrates 5 analog inputs (0–10 V), 3 analog outputs (±10 V), and a +10 V potentiometer supply, all with 12-bit resolution. Featuring a compact single-slot, all-metal enclosure with IP20 protection and 2500 VAC galvanic isolation between field and controller, it delivers stable and reliable performance in harsh industrial environments with strong electromagnetic interference and vibration. As a core multifunctional I/O component, it simplifies system design and reduces wiring complexity for SYSTEM 2005-based automation projects.

Function and Positioning

The 3AM055.6 serves as a versatile analog signal interface for B&R SYSTEM 2005 controllers, bridging the control system and analog field devices. It accurately acquires 0–10 V signals from sensors (temperature, pressure, flow, level) and converts them into high-resolution digital data for real-time monitoring and closed-loop control. Simultaneously, it converts digital control commands into ±10 V analog outputs to drive actuators such as proportional valves, frequency converters, and positioning drives. The integrated +10 V potentiometer supply enables direct connection of potentiometers for manual adjustment or feedback calibrationB& R Industrial Automation. By combining 5 inputs, 3 outputs, and potentiometer power in one compact unit, it reduces hardware complexity, wiring effort, and cabinet space, positioning it as a cost-effective, space-saving solution for small-to-medium automation systems requiring multi-channel analog processing.
