B&R 3AM050.6 Electrical Module

The 3AM050.6 is a high-performance electrical mixed analog module designed for the B&R SYSTEM 2005 series control platform. It integrates four 0–10 V differential analog input channels and four ±10 V analog output channels in a compact single-slot form factor. Featuring 12-bit resolution across all channels and 2500 VAC galvanic isolation between the field side and the system backplane, this module delivers precise, reliable signal conversion with strong resistance to electromagnetic interference. It serves as a critical electrical interface for industrial automation systems requiring simultaneous analog signal acquisition and control output.

Function and Positioning

The 3AM050.6 functions as a versatile electrical signal conversion and interface unit within SYSTEM 2005 control systems. It converts analog voltage signals from field sensors, transmitters, and measuring devices into high-resolution digital data for the controller, enabling real-time monitoring of process variables such as pressure, temperature, and flow. Simultaneously, it converts digital control commands from the PLC into standard analog voltage signals to drive actuators, valves, and other analog-controlled equipment. Its integrated design reduces the number of modules, simplifies system wiring, and lowers overall costs, positioning it as a cost-effective electrical solution for general industrial automation applications requiring mixed analog I/O.
