B&R 3AM050.6 SYSTEM 2005 Analog Mixed Module

The 3AM050.6 is a compact high-performance analog mixed module from B&R’s SYSTEM 2005 series, integrating 4 analog inputs and 4 analog outputs in a single slot. Designed for space-saving and cost-effective analog signal processing, it accepts 0–10 V differential inputs and provides ±10 V outputs, each with 12-bit resolution. Featuring galvanic isolation between field side and PLC backplane, it ensures stable and reliable signal conversion for process monitoring and closed-loop control in industrial environments.

Function and Positioning

The 3AM050.6 acts as a compact all-in-one analog signal interface for SYSTEM 2005 controllers, combining precise signal acquisition and control output in one module. It converts 0–10 V differential signals from sensors (pressure, flow, temperature, level) into digital values for the PLC, while converting digital control commands into ±10 V analog signals for actuators, valves, and variable-frequency drives. Galvanic isolation protects the control system from electrical noise and voltage spikes. Its mixed I/O design optimizes system architecture for applications requiring both monitoring and control, serving as a critical bridge between analog field devices and digital control systems.
