Solid state relays are more economical than mechanical relays because they require a much lower current to be switched. Furthermore, an SSR contains no moving parts, so they switch faster and last much longer because there is less wear. This relay can switch a current up to 40A with an input from 3V to 32V DC. The relay is equipped with 4 screw terminals. https://elecena.pl/product/27739231/opencircuit-solid-state-relais-3-32v-40a-24-380vac 2025-01-23 https://elecena.pl/product/27739231/opencircuit-solid-state-relais-3-32v-40a-24-380vac 2025-05-29 https://elecena.pl/product/27739231/opencircuit-solid-state-relais-3-32v-40a-24-380vac 2026-02-23 https://elecena.pl/product/27739231/opencircuit-solid-state-relais-3-32v-40a-24-380vac 2026-02-25 https://elecena.pl/product/27739231/opencircuit-solid-state-relais-3-32v-40a-24-380vac 2026-04-11
