3-Outlet Receiver

This has a 3-pin line input on a cord and 2 duplex sockets for the outputs. This has a limit of 5 amperes.

One of the four outlets is not switched.

They are enclosed in a dual NEMA enclosure. The low-voltage circuits are inside at the bottom. 

There are two boards: one for the receiver and ICs and a second for the relays.

The box has a 9-pin D-connector which is used both for programming the micro-controller.

The receiver is hidden at the back of the wall  unit in the living room behind our travel albums.

It is powered from a 12-V plug-in power supply.
