Industrial LCC-DN-DC1 Programmable Controller

The STI LCC-DN-DC1 is a DIN-rail mounted safety controller in Scientific Technologies Inc.'s LCC-DN family, designed to interface with STI light curtain safety devices and integrate into standard machine-control circuits. With part number 43516-0010, it operates from a 24 VDC negative-ground supply and weighs about 1.35 lb, making it a compact option for safety enclosures on the factory floor. This model is listed as discontinued by the manufacturer and is commonly referenced alongside its LCC-DN siblings, including the LCC-DN-DC2 variant; some distributors still list it for repair and replacement parts. As a dedicated light curtain controller, the LCC-DN-DC1 is used to manage light curtain safety circuits, providing a DIN-rail mounted option for facilities already using STI safety light curtains.
