Key benefits power switching: Builtin 40A relay lets the receiver control heavy electrical loads reliably, reducing the need for repeat relays or additional hardware. Longrange, obstaclepenetrating control: RF technology provides strong signal penetration through walls, floors and doors for convenient remote operation from other rooms or floors. Flexible, simple pairing: Learnable remote buttons allow custom control setups—one remote can operate multiple receivers and multiple remotes can control the same receiver. Stable, sensitive reception: receive sensitivity and stable performance ensure consistent operation with fewer missed commands. Features and performance Load capacity: 40A relay for direct control of most power electrical appliances within the relay rating. Wireless range: Up to 984 ft (300 m) in open space; reliable operation through typical household or lightcommercial obstacles. Pairing capability: Learns multiple remote controllers; each button on a remote can be learned independently for flexible combinations. Supports configuration with two remote controls for immediate multipleuser use. Reliability: Designed for longterm stable control with receive sensitivity. How this product solves problems Eliminates the need to run wiring or install additional control devices for heavy loads by providing a single, robust relaybased receiver. Reduces interruptions and missed commands through strong RF signal and sensitivity. Simplifies multiuser or multiswitch setups with flexible learnandpair functionality—no complex programming required. Compatibility and use Intended to work with RF remote controllers and compatible electrical appliances that do not exceed the 40A relay rating. Suitable for residential and light commercial applications where wireless, current switching is needed. No special tools required for pairing; each remote button can be learned and reassigned as needed for flexible control schemes. Practical use scenarios 1) Garage and workshop control: Install the receiver to switch garage lighting, outlets or motorized tools (within 40A) from a handheld remote without running control wiring. 2) Pump and irrigation control: Use the receiver to wirelessly switch water pumps or irrigation valves from inside the house; RF signal penetrates building structures for convenient operation. 3) Multiuser lighting and appliance control: Configure two remotes (or more) so family members or staff can control the same lights or appliances, or program one remote to manage multiple receivers for grouped control. Operation summary Learn mode: Put the receiver into learn mode and activate the desired remote button to pair; repeat for additional buttons or remotes. Flexible mapping: Any button on any remote can be learned to any receiver channel, enabling onetomany and manytoone control arrangements. Recommended use: Verify connected appliance current does not exceed 40A. For maximum wireless range, avoid signalblocking metal enclosures and place antenna/receiver with reasonable lineofsight when possible. This receiver provides a practical, reliable solution for wireless current switching, combining strong RF range, flexible pairing, and a 40A relay for demanding home and lightcommercial applications.
