Hardwired Wireless RF Relay Control Module 6–36v DC

📝 Wireless RF Relay Control Module 6–36v DC – 10A (433MHz)

This wireless RF relay control module is a hard-wired inline switching unit that allows you to remotely turn connected devices on or off using a paired RF remote. Operating exclusively on the 433MHz RF frequency, it delivers stable and reliable wireless control with strong signal penetration through walls, doors, and other solid objects.

Designed for DC 6–36v systems, this module is well suited to automotive, RV, marine, industrial, and security applications where traditional wired switches are impractical.

⭐ Essential Benefits

• 433MHz RF technology – stable wireless control using a dedicated RF frequency.
• Wide DC voltage support – operates from 6–36v DC including 12v and 24v systems.
• 10A switching capacity – suitable for lighting, motors, and control circuits.
• High receiving sensitivity – >97 dBm for reliable signal reception.
• Strong wireless range – 20–30m typical, exceeding 30m in open areas.
• Hard-wired inline design – installs directly between power supply and load.
• Multiple remote support – one receiver supports up to 20 transmitters without interference.

⚙️ Functionality

The relay module is hardwired into the circuit between the power source and the device being controlled. Once installed, the connected load can be switched remotely using RF control.

Supported operating modes:

• Toggle mode (factory default) – press once to turn on, press again to turn off.
• Momentary mode – relay remains active only while the remote button is pressed.

The operating mode is adjustable using the onboard learning button on the receiver.

🔌 Wiring & Installation

• Receiver operating voltage: DC 6–36v
• Relay output: Passive (potential-free) output
• Installation method: Hard-wired inline between power supply and device
• Antenna: External RF antenna for improved reception

The compact receiver is designed to be mounted inside an enclosure or control box for safe, permanent installation. For best performance, slightly extending the antenna is recommended.

🔧 Applications

Widely used in industrial control and security fields, including:

• Lighting systems
• Motors and fans
• Short and long-range on/off devices
• Wireless security and door alarms
• Automation and access control systems
• Remote switching in vehicles and off-grid setups

Multiple receivers can operate in the same area without signal interference.
