4-Channel Solid State Relay Module 5V DC to 240V AC (Omron G3MB-202P)

Control AC mains loads silently and reliably with the 4-Channel Solid State Relay (SSR) Module featuring genuine Omron G3MB-202P relays. Unlike mechanical relays, SSRs have no moving parts — making them ideal for high-frequency switching, noise-sensitive environments, and long-life automation applications.
