Function and Positioning

As a key I/O component in the B&R 2005 automation system, the 3DO650.6 is positioned to deliver flexible, isolated relay switching for a wide range of AC and DC field devices. It excels in applications requiring electrical isolation between circuits and the ability to switch higher‑voltage AC loads. The four isolated groups minimize cross‑interference and allow independent voltage domains. Built‑in LED indicators provide per‑channel status, enabling quick diagnostics. The module is ideal for safety‑related circuits and mixed‑voltage control panelsB& R Industrial Automation.
