The RF124, RF234 and RF324 units are A10 enhanced powerline carrier receivers controlling a single internal isolated contact form A relay. Relay holds last commanded state on power loss, and A10 circuitry remembers last relay state for correct status report upon power loss.

The RF series of receivers are programmable to any of the 256 X10 standard or Extended X10addresses. The RF124, RF234 and RF324 may be remote controlled by addressing its base address or its sub address, or through groups by the commands ALL LIGHTS ON, ALL LIGHTS OFF, or ALL UNITS OFF. These global commands must be configured.
