The Fotek Original 4-32VDC/24-380VAC Solid State is a non-contact high speed switching device that has a range of features focused on reliability and user safety, and is designed to use a lightweight DC voltage to safely switch high-voltage and high current circuits without exposing the user to potential leaks. The solid-state design, compared to Electro-Mechanical Relays, ensures that there is no actual movement within the enclosure, which dramatically enhances the efficiency and lifespan of these Relays, while at the same time ensuring silent operations.

This SSR-40DA Terminal Type unit uses a Zero Cross Trigger control method to control between 24V and 380V AC circuits, which would typically cause serious damage to users if a leak or fault occurs. This not only protects users from electrical harm, but also allows for devices and machinery to be operated remotely. Whether you want to add an extra layer of protection on a CNC machine, or are simply eager to be able to turn your coffee machine on via WiFi from the comfort of your couch, these Solid State Modules are a reliable and cost-efficient choice.
