RS PRO Solid-State Relays - Triac Output
From the trusted brand RS PRO comes a range of solid-state relays designed to provide the very best performance via a Triac output switching element. These bidirectional devices are capable of controlling AC power by switching both halves of the AC waveform. They can switch AC loads, such as heaters, lamps, motors, and other devices that require precise control of power levels.
Why would you choose a Triac Solid-State Relay?
Solid-State Relays are panel mount/surface mount relays, widely used in industrial switching applications such as control of heaters, motors, solenoid, lighting, and microcontroller-based systems. SSR switching is preferred due to high reliability and long life and in electrically harsh environment. Ratings are offered starting from 10 Amps to 40 Amps for 240- and 440-volts applications.
