U122 UNIT SSR Solid-State Relays
m5Stack U122 UNIT SSR Solid-State Relays are different from traditional electromagnetic relays in that the switching life is much longer than that of electromagnetic relays. Integrated MOC3043M optocoupler isolation and zero-crossing detection support input 3.3V to 5V DC control signal and control-output output single-phase 220-250V AC power.
