Function
Zero-voltage AC switching, optical input-output isolation, LED status indication, built-in TVS surge protection, reinforced insulation for safety, reliable switching for various industrial application
The SSR OCR-D32-A480-75A-ZL is a high-performance, zero-crossing solid state relay designed for reliable AC switching in demanding industrial environments. Utilizing semiconductor technology instead of mechanical contacts, this relay features optical isolation between input and output for enhanced safety and signal integrity. When a control voltage of 4–32 VDC is applied, the relay switches loads up to 75A within a wide output voltage range of 24–480 VAC.
Key features include zero-voltage switching, which minimizes electrical noise and inrush currents, making it ideal for sensitive resistive, inductive, and capacitive loads. The device also offers LED input indication for clear status monitoring, built-in TVS surge protection for enhanced durability, and reinforced insulation between the housing (including the base plate) and high-voltage circuitry for maximum operational safety.
Widely used in electric furnace heating, thermostat systems, CNC machinery, plastics, food, packaging, textile machinery, petrochemical instrumentation, and other automation control fields, the SSR OCR-D32-A480-75A-ZL delivers robust, maintenance-free switching for a broad range of industrial applications.
