This series of industrial grade solid-state relays is a contactless on-off electronic switch, with two terminals for input control and the other two for output control. The middle uses photoelectric isolation, and the input and output uses photoelectric coupling. By adding a DC or pulse signal to the input terminal, the output terminal can transition from a off state to a on state (blocked when there is no signal), thereby controlling a larger load. The entire device has no movable components and contacts, and can achieve the same functions as commonly used mechanical electromagnetic relays.

Widely used in industrial automation fields such as electric furnace temperature control, rubber and plastic machinery, printing machinery, packaging machinery, fountain control, CNC machine tools, stage lighting, and so on.

Product features:
