B&R 3AM055.6 Mixed Module (Electromechanical)

The 3AM055.6 is a high-density electromechanical analog mixed module from the B&R SYSTEM 2005 series, engineered for integrated analog signal processing and reliable electromechanical integration in industrial automation. It combines 5 differential analog inputs (0–10 V), 3 analog outputs (±10 V), and an integrated +10 V potentiometer supply, all with 12-bit resolution. Built with a rugged all-metal enclosure and IP20 protection, it features robust electromechanical design for DIN rail mounting and backplane connection, delivering superior vibration resistance and mechanical stability. With 2500 VAC galvanic isolation between field circuits and the controller, it ensures stable electrical performance in harsh industrial environments, serving as a core electromechanical I/O component for SYSTEM 2005 platforms.

Function and Positioning

The 3AM055.6 functions as a critical electromechanical interface bridging control systems and analog field devices in industrial automation. It precisely acquires 0–10 V signals from electromechanical 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 electromechanical actuators such as proportional valves, frequency converters, and servo drives. The integrated +10 V potentiometer supply enables direct connection of manual control potentiometers for electromechanical adjustment. Its rugged electromechanical design ensures secure mounting, reliable backplane communication, and stable field wiring connection, positioning it as a cost-effective, mechanically robust solution for small-to-medium automation systems requiring integrated multi-channel analog processing and durable electromechanical integration.
