Selecting the Proper Amperage

To ensure you choose a board with the correct relay amperage for your load requirements, refer to Choosing a Proper Amperage.

Need a 4-channel Ethernet relay for independent device control? These ProXR Lite boards let you switch two relays remotely using a built-in web interface.

Ethernet Relay

Ethernet Relays allow you to control devices by sending commands through your local network or over the internet. The 3rd Generation Ethernet interface connects seamlessly to a router via a standard CAT5 cable, where it's assigned an IP address. Once on the network, you can send commands to control the relay both within your local network or remotely over the internet. The Gen3 Ethernet module is custom-designed specifically for NCD devices, ensuring optimal compatibility and performance.

Key Features

  • Remote Control: Easily control relays from within your local network or from anywhere via the internet.
  • Seamless Network Integration: Connects via standard CAT5 cable and automatically receives an IP address on your router.
  • Customizable Interface: Supports a wide range of programming languages and offers software for non-programmers.
  • NCD Compatibility: Optimized for use with NCD devices for enhanced reliability and performance.

Gen3 Web Relay

Previously offered as separate modules, the Gen3 Ethernet module now includes built-in web control capabilities. With the Gen3 module, you can store and manage web pages directly on the device to control the relays. Pre-built web pages are available for immediate use and can be uploaded using free configuration software. If you prefer, you can modify these pages in your favorite HTML editor and upload custom pages tailored to your needs. The available web pages are designed to match the number of relays installed on your board.

4-Channel WiFi Relay Series (ProXR Lite)

Ethernet Relay4-Channel Ethernet Relay Boards are available in the non-expandable ProXR Lite version. While ProXR Lite boards cannot be expanded, they still support the full ProXR Command Set - the industry's most powerful relay control protocol.

- Program in nearly any language.
- Send precise relay commands.
- Control with confidence.

Select Your Relay Type & Amperage

Choose the 4-channel Ethernet relay controller that matches your load requirements:
  • SPDT Relays: 5A, 10A, or 20A
  • SPST Relays: 30A

💡 Relay Pros Pro Tip:

If you're controlling high-current loads like motors or heaters, always choose a relay with extra amperage headroom. Running a relay at its maximum rating can shorten its lifespan.
