Selecting the Proper Amperage

For more information on selecting a board with the correct relay amperage for your application see Choosing a Proper Amperage.

This 24-channel WiFi relay board gives you 24 individually controlled relays and the ability to expand up to 256 relays, making it ideal for scalable automation, industrial control, and custom relay projects.

NextGen WiFi Relay Interface

The NexGen WiFi is NCD's second-generation communications module that combines WiFi, Bluetooth, USB, and MQTT into one powerful interface. Designed for flexibility, it lets you configure features through an easy-to-use web interface in Soft AP mode, so your system works exactly the way your application needs it to.

Selecting a WiFi Relay Board Series

WiFi Relay BoardThe 24-Channel WiFi Relay Boards are built on the ProXR platform, featuring the industry-leading ProXR Command Set for advanced relay control.

Every ProXR controller is expandable up to 256 relays, making it easy to start with 24 relays today and grow your system as your project evolves.

Expansion boards can be added at checkout or anytime in the future.

Select Your Relay Type & Amperage

Choose the 24-channel WiFi relay controller that matches your load requirements:
  • SPDT Relays: 5A, 10A
  • DPDT Relays: 1A, 3A, or 5A
