RF Controlled 4-Channel Relay Module (Wireless Smart Switching)

Cut the wires and take absolute control over your electrical systems from a distance with the RF Controlled 4-Channel Relay Module. Precision-engineered by Muonix, this wireless switching solution pairs a heavy-duty 4-channel relay board with a high-performance Radio Frequency (RF) receiver module.

Designed to operate seamlessly through walls and doors without requiring line-of-sight, this module lets you remotely toggle up to four independent electrical appliances—such as garage doors, security gates, household lights, water pumps, or automated machinery panels. Manufactured under strict lead-free guidelines, it delivers a completely standalone, secure, and industrial-grade wireless control grid right out of the box.

Key Features

• Long-Range RF Connectivity: Operates on the highly stable and standard radio frequency spectrum (typically 315MHz or 433MHz), allowing secure wireless signaling through walls, floors, and barriers up to 50–100 meters in open spaces.

• 4 Independent Switching Channels: Control four separate AC or DC electrical loads completely independently from a single handheld RF remote transmitter.

• 3 Adaptable Working Modes: Easily configure the receiver board to function in Inching/Momentary (turns on while pressing button), Self-Locking/Toggle (press once to turn on, press again to turn off), or Interlocking/Latched (one button turns a channel on, another button turns it off) modes.

• Simple Wireless Pairing: Features an onboard learning button that allows you to easily pair or clear remote controllers in seconds without complex programming.

• Complete Hardware Isolation: Built with independent relay coils that physically isolate the low-voltage RF control signals from high-voltage main lines, protecting your wireless circuits from inductive feedback and surges.

Technical Specifications

Lead-Free & Soldering Safety

• 100% Lead-Free PCB: The base circuit board is constructed from eco-friendly, lead-free materials, aligning fully with global industrial safety and environmental practices.

• Factory Pre-Soldered Components: All heavy-duty terminal blocks, RF sub-modules, and power traces are mounted using high-grade, lead-free solder wire to ensure optimal electrical conductivity.

• Enhanced Thermal Strength: The premium lead-free solder joints offer superior resistance against crystallization and structural drying, even when cycling heavy 10A electrical loads over extended periods.

Hardware Configuration & Working Modes

You can customize how the relays react to your remote buttons by adjusting the onboard header pins/jumpers:

1. Momentary (Jog): Press and hold the remote button to turn a channel ON; release the button to turn it OFF.

2. Toggle (Self-Locking): Press the remote button once to turn a channel ON; press the same button again to turn it OFF.

3. Latched (Interlocking): Press Button A to turn Channel 1 ON (all other channels drop OFF); press Button B to turn Channel 2 ON, and so forth.

Load Output Mapping (3-Way Screw Terminals):

Each of the 4 channels features a dedicated terminal block containing:

• NO (Normally Open): The circuit stays disconnected/open until an RF wireless command triggers the relay to close.

• NC (Normally Closed): The circuit stays connected/closed by default until wireless RF logic triggers it to open.

• COM (Common Terminal): The central main power wire from your load connects directly here.

Common Applications

• Wireless Home Automation: Remotely operate ceiling fans, chandeliers, multi-tier outdoor lighting arrays, and landscape water fountains.

• Security & Access Control: Wire directly to motorized sliding gates, automated garage shutters, rolling curtains, or electromagnetic door locks.

• Industrial Wireless Control: Act as an intermediate remote receiver box to let operators trigger heavy machinery, sirens, or conveyor belts from a safe distance.
