Pico Expansion Modules extend the power and reach of the Poco Digital Lighting Control system making it possible to control other manufacturers luminaires, lighting accessories and devices that do not have the sophisticated PLI technology built-in. The Pico S8 moudule provides the ability to assign Poco virtual switch commands to physical mechanical switches (up to 8 max). This means that your MFD can remain on a dedicated screen, or even be turned off, and a physical switch will activate the virtual switch command through the Poco module.
