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 calibration. 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.
