16-Channel ENC28J60 Network Relay Module | Remote Power Control

16-Channel ENC28J60 Network Relay Module

Take full control of your electrical switching infrastructure from anywhere on your network. The diymore 16-Channel ENC28J60 Network Relay Module is a powerful, router-controlled relay board built on a 32-bit platform that lets you switch up to 16 independent circuits via any standard web browser — no special software required.

Whether you're managing smart office automation, surveillance system power, industrial equipment, or unattended remote installations, this module delivers reliable, low-power centralized control over your entire electrical switching network.

Key Features

• 16 Independent Relay Channels — control up to 16 separate circuits individually via HTTP commands
• Browser-Based Control — configure and operate directly through any Internet Explorer-compatible browser; no dedicated software needed
• Internet & LAN Remote Control — operate over the internet or an internal router for maximum flexibility
• 32-Bit System Architecture — ensures fast, stable, and responsive switching performance
• 100,000-Cycle Electronic Switch Lifespan — built for long-term, high-frequency use
• Wide Operating Temperature Range — -30°C to 85°C, suitable for demanding environments
• Low Power Consumption — energy-efficient design for continuous operation
• ENC28J60 Ethernet Controller — proven, reliable network interface for stable connectivity

Technical Specifications

HTTP Command Reference

Control each relay individually using simple HTTP GET commands from any browser or automation script:

• http://IP/Port/00 — Relay 01 OFF  |  /01 — Relay 01 ON
• http://IP/Port/02 — Relay 02 OFF  |  /03 — Relay 02 ON
• (Continues in pairs through Relay 16: commands /30 = OFF, /31 = ON)
• http://IP/Port/99 — Returns current status of all 16 relays in ASCII (MSB = Relay 1, LSB = Relay 16)

Modify IP: http://IP/Port/41 — Relay-01 value cannot be 0; octets 01–04 cannot exceed 255; port cannot be 0.

Restore Defaults: Press and hold the button until the LED lights up, then release. The module resets to IP: 192.168.1.4, Port: 30000.

Ideal Applications

• Office and commercial building automation
• Surveillance and security system power management
• Hotels, shopping malls, cafes, and karaoke venue timer management
• Industrial equipment and factory power control
• Unattended remote stations (underground pipelines, mining, marine, aviation facilities)
• Smart home and centralized management systems
• Test equipment power sequencing

⚠️ Safety Note: When connecting to high-voltage power modules, carefully verify all wiring before energizing to prevent equipment damage from short circuits.

Frequently Asked Questions

Q: How do I connect and configure the 16-channel ENC28J60 network relay module for the first time?

A: Connect the module to your router via an Ethernet cable and power it with DC 5.5V at up to 2A. Set your PC's IP address to the same subnet (e.g., 192.168.1.x). Then open a browser and navigate to http://192.168.1.4:30000 to access the built-in control interface. From there you can toggle all 16 relay channels, check relay status, and modify the module's IP address and port settings.

Q: Can I control this relay module over the internet, not just a local network?

A: Yes. The ENC28J60 network relay module supports both LAN (internal router) and internet-based remote control. You will need to configure port forwarding on your router to expose the module's IP and port to the internet, after which you can send HTTP commands from any device with internet access to switch your relay channels ON or OFF remotely.

Q: What happens if I need to reset the module to factory settings?

A: To restore factory defaults, press and hold the onboard button without releasing it until the LED lights up, then release the button — the LED will turn off to confirm the reset. The module will return to its default IP address of 192.168.1.4 and port 30000.

Q: Is this relay module suitable for industrial or harsh-environment use?

A: Yes. The module is rated for an operating temperature range of -30°C to 85°C, making it suitable for demanding environments including factories, underground pipelines, mining equipment, marine vessels, and aircraft station rooms. Its electronic switches are rated for 100,000 cycles to ensure long-term reliability.
