8 Channel Relay Board for Arduino Pro Mini-compatible
If you're looking for a compact and powerful method of controlling up to eight relays with an Arduino-compatible board, then this 8 Channel Relay Board for Arduino Pro Mini-compatible boards from PMD Way with free delivery solves your problem.
The board is based around an Arduino Pro Mini-compatible, which allows you to easily write controlling code using the easy Arduino ecosystem, or with AVR C or assembly language.
The board is equipped with eight relays capable of switching up to 30 V DC or 250 V AC at 10A. There is also eight inputs which are fully isolated using optocouplers (low level trigger, NPN type), a four digit seven segment numeric LED display - and all inputs and outputs are easily accessible with terminal blocks. And four tactile buttons for use with your interface.
Using this board and your own code, you can control eight relays, accept digital inputs from eight devices, create your own displays using the four digits, and accept user input with the buttons. Consider this to be a very inexpensive alternative to a simple PLC-based relay control system.
Use the options menu to select between:
- The relay board by itself (you already have a Pro Mini or compatible board and USB interface)
- Relay board WITH Pro Mini and USB-TTL adapter. You will need female to female jumper wires to connect the Pro Mini to the USB adapter.
