Product information

Description

The FF ETR-868 Wireless Relay Transmitter and Receiver Radio Controlled 868MHz 230V is a comprehensive wireless relay system designed for remote switching and automation applications. This setup includes both a transmitter and a receiver operating at a radio frequency of 868 MHz, powered by a standard 230V supply. It enables reliable wireless control of various electrical devices and circuits, making it a practical solution for modern residential, commercial, or industrial installations where distance or wiring constraints make traditional switches impractical.

Advantages

This wireless relay transmitter and receiver system offers seamless remote operation without the need for complex physical cabling between the control point and the target device. Operating on the 868 MHz frequency helps ensure a stable signal transmission with reduced interference compared to lower frequency bands. The 230V power supply compatibility allows for direct integration into standard electrical networks, providing a versatile approach to automating lighting, motors, pumps, and other electrical loads in diverse environments.

Suitable for

  • Wireless remote control of residential lighting and electrical circuits
  • Automating commercial ventilation or heating systems
  • Operating industrial machinery and auxiliary equipment from a distance
  • Retrofitting existing electrical setups where adding new wires is difficult

When it may not be suitable

This device may not be suitable for applications requiring extremely rapid response times in safety-critical emergency systems or environments with heavy electromagnetic interference that could disrupt the 868 MHz radio signal. Additionally, installations requiring battery-powered mobility on both ends are not supported, as the system relies on a 230V power supply.

Key specifications

  • Radio controlled wireless operation at 868 MHz
  • Includes both transmitter and receiver units
  • 230V power supply compatibility
  • Designed for remote switching and automation
  • Suitable for residential, commercial, and industrial use

How to use

Installation requires connecting the receiver unit to the 230V power supply and wiring the controlled electrical load to the relay output terminals. The transmitter must be properly paired with the receiver according to the system guidelines to establish a secure radio link. Once installed and powered, activating the transmitter sends a radio signal at 868 MHz to the receiver, which then opens or closes the relay circuit to switch the connected device on or off.

What to consider before purchase

  • Verify that your local power supply matches the 230V requirement
  • Check the operating distance and physical barriers between the transmitter and receiver locations
  • Ensure the electrical load of your device does not exceed the relay capacity
  • Confirm whether professional electrician installation is required for your specific setup

For optimal performance, position the transmitter and receiver to minimize physical obstructions and metal interference that can affect the 868 MHz radio transmission range.

Product comparison

In this overview, the FF ETR-868 Wireless Relay is compared with several alternative options from the same brand, including the FF Wi-R1S1-WP smart Wi-Fi socket and a series of FF TOM miniature split-core current transformers (models 150-5, 200-5, 250-5, and 600-5). All these products share a common focus on electrical management and automation, but their practical purposes differ significantly: the FF ETR-868 is a radio-controlled relay system designed for wireless switching and automation, the Wi-R1S1-WP offers app-based control with energy monitoring over Wi-Fi, and the TOM transformers are dedicated non-invasive sensors for measuring electrical current without disconnecting circuits.

⚙️ The specifications and operational capabilities of these devices are compared below to highlight their core differences and intended roles.
