Function and Positioning

As a high‑isolation, high‑power relay output component in the B&R 2005 automation system, the 3DO760.6 is positioned to deliver maximum flexibility and safety for mixed AC/DC loads. Its single‑channel isolation eliminates cross‑talk between channels, while the combination of changeover and normally open contacts supports diverse wiring schemes. Built‑in per‑channel LEDs enable rapid status verification and on‑site diagnostics, making it ideal for high‑power contactors, valves, and auxiliary equipment requiring independent channel isolation.
