power wireless remote switch with 30A relay Why you need it: Safely control current appliances from a distance without running wiring. Ideal for equipment that must be switched on/off remotely or from hardtoreach locations. What makes it stand out: A 30A relay handles heavy loads, a 433MHz radio link penetrates floors and doors, and a learning button provides flexible code management and four operating modes. Key benefits and functions power handling: Builtin 30A relay supports heavy electrical loads for safe, stable control of mainspowered appliances. Simple installation: Mount the receiver inline between the device and its power supply. No complex setup—once wired, the receiver is controlled by the remote to turn the load on or off. Reliable wireless reception: Uses 433MHz RF that can penetrate floors and doors; reliable control within a usable range (maximum up to 328 feet under open conditions). Flexible control modes: Four selectable modes—momentary (presstoactivate), toggle (alternate on/off), latched (maintain a state until changed), and delay time (automatic off after a set interval)—to match different application needs. Learn/delete codes: The learning button lets you erase the old code and relearn a code easily for pairing or security changes. Performance and compatibility Relay rating: 30A (suitable for many power mains appliances). Verify appliance current and local regulations before use. Radio frequency: 433MHz with a maximum practical range up to 328 feet in open conditions; walls and floors reduce range but signal can penetrate typical building structures. Function: Acts as an inline remotecontrolled switch between power source and load; controlled remotely by compatible 433MHz transmitters. Installation note: Designed to be installed in series with the device and its power supply. Ensure proper wiring and grounding according to local electrical codes. How the modes work (quick reference) Momentary: Output is active only while the remote button is held. Toggle: Each remote press alternates the output between on and off. Latched: Output changes state and remains until another command changes it. Delay time: Output turns on and then automatically turns off after a preset delay. Practical applications Pool or spa pump control: Remotely turn pumps on or off without going outside to the equipment area. Workshop and garage tools: Safely control current tools or workshop motors from a workbench or doorway. Home HVAC or water heaters: Switch hardtoreach or frequentlyadjusted appliances without rewiring switches or running control lines. Safety and installation tips Confirm the appliance current does not exceed the 30A relay rating. Follow local electrical codes and, if unsure, have a qualified electrician perform wiring and installation. Test signal range and mode operation after installation to ensure reliable control in your environment.
