B&R 3AM051.6 Analog Mixed Module

Product Introduction

The 3AM051.6 is a high‑density analog mixed module from the B&R SYSTEM 2005 series, engineered for accurate current signal acquisition and control in industrial automation. It provides 4 analog inputs and 4 analog outputs, all designed for 0–20 mA DC signals with 12‑bit resolution. Built in a single‑slot form factor, it features 2500 VAC galvanic isolation between field circuits and the backplane, ensuring reliable operation in electrically noisy environments. As a key I/O component for the SYSTEM 2005 platform, it delivers stable and precise analog signal conversion for process monitoring and closed‑loop control tasks.

Function and Positioning

The 3AM051.6 acts as a dedicated current‑loop interface for B&R SYSTEM 2005 controllers, connecting 0–20 mA field sensors and actuators to the control system. It converts analog current signals from pressure, flow, temperature, and level transmitters into high‑resolution digital values for real‑time process monitoring. Simultaneously, it converts digital control commands from the PLC into 0–20 mA output signals to regulate valves, frequency converters, and other current‑driven devices. By integrating input and output channels in one module, it reduces hardware complexity, simplifies wiring, and optimizes system costs, serving as a versatile solution for integrated analog I/O in general industrial automation.
