1Channel Relay Module A compact single channel relay that lets a low voltage control signal switch a higher power load. It provides electrical isolation between control and load circuits and is suitable for home automation and light industrial use. Function: Form C contact (Common, Normally Open, Normally Closed) for flexible switching Coil voltage: 5V, 12V or 24V coil versions Load rating: Contacts rated up to 10 A at 250 VAC or 30 VDC; supports resistive and moderate inductive loads Size and materials: Compact plastic enclosure with screw terminals for easy wiring Compatibility: Works with standard logic levels from microcontrollers and automation controllers; simple on/off drive Performance: Reliable switching, fast response, low drive current on the control side Safety and reliability: Coil and contact isolation protect the control circuit; durable construction for continuous operation Use scenarios: Home automation: switch a ceiling light or ventilation fan from an Arduino or Raspberry Pi Small panel controls: drive a 230 VAC small pump or blower in a compact control box Building automation: trigger a damper or humidifier from a PLC or control system Note: Verify coil voltage and load rating before use
