Traditions (Generic) ESP8266 24V 32-way relay development board computer power cord

SKU CH-WWGS-G6R86

A DC 24 V ESP8266 development board with 32 relay channels for Wi-Fi control projects

  • ESP8266 WiFi module enables wireless control of connected devices
  • 32-way relay array switches multiple circuits from a single board
  • DC 24 V power supply simplifies integration with industrial voltage rails
  • ESP-12F core provides a ready-to-program platform for custom firmware

ESP8266 32-way relay development board

This board combines an ESP8266 WiFi module with 32 relay outputs for switching tasks. It runs from a 24 V DC supply and uses the ESP-12F module for wireless connectivity. The design targets developers building automation or remote-control prototypes.

Sustained operation with 24 V supply

Under continuous load the 24 V input powers both the ESP8266 and all relay coils without a separate regulator. Heat from multiple energised relays is dissipated through the PCB copper area. The WiFi link remains active while relays switch, so network commands are processed without interruption.

Questions about this item

How much power does the 32-way relay board draw when all relays are energised all day?

The board runs from a 24 V DC supply; the ESP8266 module itself draws only milliamps, while each of the 32 relay coils adds its rated coil current when active.

What external items are required before the ESP8266 32-way relay board can operate?

You need a 24 V DC power source capable of supplying the combined relay coil current, a USB-to-serial adapter or programmer for flashing the ESP8266, and wiring to the devices you intend to switch.
