5V Relay SPDT Suger cube relay only– Opto-Isolated Relay Board
Switch high-power electrical loads safely using low-voltage digital signals with this compact 5V SPDT Sugar Cube Relay. This industry-standard 5-pin electromagnetic relay features a single-pole double-throw configuration, allowing your microcontrollers to isolate and toggle both Normally Open (NO) and Normally Closed (NC) electrical paths. Operating on a low 5V DC coil voltage, it triggers directly via standard optocoupler drivers and transistor switches on development boards like Arduino, ESP32, or Raspberry Pi. Housed in a sealed, miniature plastic casing—affectionately known as a sugar cube frame—this durable relay handles heavy loads up to 10A at 250V AC or 30V DC. It is the ultimate choosing component for home automation systems, smart appliance networks, automated circuit breakers, and industrial control panels.
