Compact RF Wireless Relay Receiver — key benefits and specs What this product does Compact RF receiver with a cased relay for protected, longlasting switching of lowvoltage DC loads. Designed for installation in small or concealed spaces and for flexible remote control of devices powered from DC 3.5 V to 12 V. Why you need it Saves installation space: small footprint allows mounting inside junction boxes, enclosures, or behind panels where space is limited. Protects the relay and extends service life: the relay is enclosed in a casing to reduce exposure to dust and mechanical damage. Reliable remote control: RF technology provides a stable wireless signal that can pass through walls, floors and doors, allowing steady control from anywhere within the reliable range. Simple and safe operation: unit ships in latched mode by default for straightforward on/off control of connected loads. Key specifications Working voltage: DC 3.5 V to DC 12 V. Maximum load: 1 A (recommended working load less than 700 mA for performance and longevity). Wireless range: up to 30 m lineofsight (range reduced by obstacles such as walls and floors). Relay: enclosed/cased relay for protection. Practical features Small size for easy, concealed installation in tight spaces. Stable RF signal for reliable remote switching through typical building materials. Default latched (toggle) operating mode for simple on/off control. Compatibility and typical applications Intended for DCpowered devices and circuits within the stated voltage and current limits. Ideal for applications such as: Outdoor advertising signs and channel letters where a concealed receiver switches LED modules from a remote transmitter. LED lighting and accent strips inside fixtures or coves where the receiver is hidden and controlled remotely. Remote switching of small engineering or industrial control circuits and interfaces that require a compact, protected relay. Installation and usage notes Ensure the controlled device draws no more than the recommended load (preferably under 700 mA) to maximize reliability. Verify the power source provides DC 3.5–12 V. Test RF range in the installation environment; walls, floors and metal enclosures will reduce effective range from the maximum 30 m lineofsight specification. Unit is supplied in latched mode by default for on/off toggling of the connected circuit. This product offers a compact, protected relay receiver with stable RF control for lowvoltage DC applications where space is limited and reliable remote switching is required.
