Dedicated board both for home automation with Home Assistant and in standalone with other programmes such as Arduino, OpenPLC, etc.
It can also be used in other areas outside home automation.
Features of the board by RG4tech
- 12V or 24V DC power supply (depending on components fitted)
- 8 opto-isolated inputs (12-24V voltage depends on resistors fitted)
- 8 relay outputs (with common for every 4 relays, 1 relay configurable as NO/NC)
- 1 LED output on board
- 1 input for DS18B20 temperature sensor on board
- 2 freely configurable analogue inputs (0-5V, 0-10V, 0-20mA) depending on resistors fitted
- analogue inputs conditioned by LMV358
- overvoltage protection by Transzorb and zener
- filter inductance on 5V supply
- filter inductance on analogue circuit supply
The same board, via adapter, can also accommodate an Arduino Nano, Arduino Pro Micro or Blue Pill STM32
