RS-485 Switch Board (110727-91)
Our ElektorBus series has shown how much interest there is in home automation applications. This small circuit board can switch two AC (230 VAC) loads. Also, two of the inputs to the on-board microcontroller are brought out to terminals so that the state of two switches can be read back. The board works with the ElektorBus and so is an ideal building-block for a home automation system controlled from a PC, tablet or smartphone.
