The Edwards Signaling 200 Class 70mm Stacklight is a versatile signaling device that may contain up to five light modules, or four light modules and one sounder module in a single, integrated stack. The lens modules are available with LED, Incandescent or Xenon strobe light sources, and in red, amber, blue, green, yellow and white. Options for Steady Burn, Flash or Multi-Mode are available. The lenses are made from a self-extinguishing polycarbonate material and are scratch and impact resistant. Optional piezoelectric and magnetodynamic sounder modules complement the visual signals of the Stacklight, offering several audible tones depending on the model chosen.

The sound module has been designed so that it is always in the top position of the Stacklight. The 200 Class 70mm Stacklight features an interlocking system for quick assembly without any tools. It is available in industrial gray or basic black and offers multiple voltage ranges to provide solutions for most industrial applications, while also meeting machine builder and OEM requirements.
