4 Output Channel SSR Solid State Relay 5V Module
300.00 EGP
4-Channel Solid State Relay (SSR) Module operates at 5V DC control voltage and provides optically isolated AC/DC switching (up to 240V AC / 100V DC per channel). Unlike mechanical relays, SSRs offer silent, spark-free operation with ultra-fast switching speeds, making them ideal for industrial automation, smart home systems, and precision control applications.
