Choosing Your 8-Channel WiFi Relay

WiFi Controlled Relay8-channel WiFi relay boards are available in ProXR Lite and ProXR versions:
  • ProXR Lite - Non-expandable, streamlined design
  • ProXR - Expandable up to 256 relays
Both versions use the same firmware and support the full ProXR Command Set, giving you identical control capabilities. The difference is expandability.

Select Your Relay Type & Amperage

Choose the 8-channel WiFi relay controller that matches your load requirements:
  • SPDT Relays: 5A, 10A, or 20A
  • SPST Relays: 30A
  • DPDT Relays: 1A, 3A, or 5A (ProXR only)

ProXR Lite vs ProXR
  • ProXR Lite: Non-expandable, streamlined design for fixed-size projects
  • ProXR: Expandable up to 256 relays for growing systems
  • Both: Same firmware, same ProXR Command Set, same control features
💡 Relay Pros Pro Tip:
If you think your project might grow, choose the ProXR version. You'll start with 8 relays today and expand up to 256 later - without replacing your controller.
