WAGO’s industrial switches feature a redundant power supply and switchable ring redundancy providing uninterruptible data communication. With a short recovery time of under 20 ms, the Xpress Ring increases your process reliability. The productivity and network availability of your machines and systems is always ensured. In addition to communication link redundancy, a redundant power supply – which can also be monitored using an alarm relay – is integrated into the switches. Even if the power supply fails, communication is not interrupted.
