SSR-80DA Solid State Relay 3V~32VDC to 24V~380VAC

From the shop's description

SSR-80DA Solid State Relay 3V~32VDC to 24V~380VAC The SSR-80DA Solid State Relay is an industrial-grade switching device designed to control high-power AC loads using a low-voltage DC input signal. With an input control range of 3–32V DC, it can be directly driven by microcontrollers, PLCs, temperature controllers, or automation systems. Unlike mechanical relays, the SSR uses semiconductor switching technology, providing silent operation, fast response, and long service life without mechanical wear. Built with an insulated aluminum base for efficient heat dissipation, the SSR-80DA is suitable for high-current applications such as heaters, motors, lighting systems, and industrial equipment. Its optical isolation between input and output enhances safety and protects control circuits from high-voltage interference. For high-load operation, mounting on a heat sink is recommended to ensure reliable performance. Features: Optical isolation between control and load circuits. Silent operation with no mechanical contacts. Long operational life and high reliability. Fast switching response. Built-in LED status indicator. High surge current capability. Aluminum baseplate for efficient heat dissipation. Compatible with microcontrollers, PLCs, and automation systems.
