RS485 19.2K baud Double isolated design provides isolation from the main control computer. Switches have no delay as is associated with X10 switches. Standard 3way and 4 way switches may be used.
Switches work even if the control computer is shut down.
LEDs indicate current state of circuit. 5 control circuits are provided with each controller board. If dimming is required then a separate dimmer switch may be wired in series with the relay. Express PCB to get the boards.
