This module (shield) is designed for installation on electrical switchboard. It features 4 electromagnetic relays to control almost any household electric device: lights, roller shutters, electrical sockets. It also uses 4 analog current sensors to provide independent measurement for every output. It is case compatible with Raspberry Pi (at least bottom part of the case fits). Revision 2 also features full optoinsulation with a possibility to power electromagnetic coils from separate power source.
To use this module you need a RS485 MCU Module.
Be careful with this module! It operates with 230 VAC and can be dangerous when handled inappropriately!
We will place typical questions and answers here, if they occur.
See RS485 MCU Module page for firmware.
Case .stl files are available in design files section.
