relay is an electrically operated switch that can be turned on or off, letting the current go through or not, and can be controlled with low voltages, like the 5V provided by the Arduino pins. Controlling a relay module with the Arduino is as simple as controlling any other output as we'll see later on.

Features:

  1. Supply voltage: 5V
  2. IO port level: high-level 3.3V
  3. Communication method: serial communication (TTL level), RS485 communication (MAX3485)

This control panel has already downloaded the default matching program from the factory. Users only need to connect to the serial port (P6 port) of the relay board through the USB to TTL downloader to debug (download). 

  • With a single-chip controller, you can customize the control mode according to individual needs;
  • With MAX485, can achieve ultra-long-distance communication control, multi-machine cascade communication, smart home is a good helper;
  • With optocoupler isolation and freewheeling diode to ensure the stability of the plate system;
  • 5 relays work independently, and can be controlled by normally open and normally closed ports;
  • With 5V DC power supply, communication integrated interface, download the program to complete the update;
  • With independent relay control port, do not need the single-chip control on the board, directly receive the external signal is the relay work

Package Includes:

  • 1x  5-Way Relay Module Optocoupler Isolation With Single-Chip RS485 Communication UART Serial Port TTL Communication
