Do you need a visual alert to boost safety in your workplace? Opt for this beacon tower from Rockwell Automation's Allen Bradley range. It has a blue lens that usually indicates a safety protocol should be followed. You can use it to indicate the status of anything from push buttons to large-scale machinery, as it accepts a standard supply voltage of 24V AC/DC. Controlling the rotation speed is easy, thanks to a DIP switch that lets you choose between 90 and 180rpm. Industries including mining, packaging and construction use light modules like this one.
