Function and Positioning

As a dedicated AC output component in the B&R 2005 automation system, the 3DO690.6 is positioned to provide efficient, isolated switching for 120 VAC loads. Its triac-based design supports zero‑crossing switching, minimizing electrical noise and extending load service life. The two isolated groups reduce cross‑interference and allow separate power domains. Built‑in LED indicators offer per‑channel status for quick diagnostics, making it ideal for AC‑driven devices and lighting control.
