Product: 1 Relais (single relay) What it does Acts as an electrically controlled switch that opens or closes a circuit when its control input is activated. Allows a low-power control signal to switch higher-power loads while keeping control and power circuits isolated. Key benefits Protects control electronics by isolating load currents from the control circuit. Enables safe switching of motors, lights, pumps, solenoids and other loads without routing high current through sensitive controllers. Simplifies circuit design: one compact component handles on/off switching and isolation. Reduces wear on manual switches and controller outputs by taking on the switching duty. Important attributes to check before use Function: single relay for switching and isolation. Compatibility: confirm coil voltage, contact current rating, contact configuration and pin layout against your system requirements before installation. Size and mounting: designed as a single relay unit; check physical dimensions and terminal style to ensure fit in your socket or PCB footprint. Material and performance: standard relay construction—metal contacts and insulating housing—intended for reliable electrical switching. Verify contact material and expected lifetime from the datasheet for your application. Practical use scenarios Automotive accessory control: use the relay to switch headlights, auxiliary lights or horns with a low-current dashboard switch or controller. Industrial or workshop equipment: control pumps, fans or small motors from a PLC or switch panel while keeping the control circuitry isolated from load currents. Home automation and HVAC: integrate the relay into a smart controller to switch heaters, compressors or valves safely without exposing the controller to high current. Installation and safety notes Match relay coil voltage and contact ratings to your circuit before applying power. Ensure proper wiring and secure terminals to prevent loose connections or overheating. Follow applicable electrical codes and safety practices when integrating into live systems. If you need specific coil voltage, contact ratings, pinout or mounting details, consult the product datasheet or the seller’s specification to confirm compatibility with your application.
