ABSTRACT:
A line-powered module that is selectively operable in one of a plurality of modes of operation based upon the value of a selection signal. The line-powered module includes a control unit that selectively operates the module in one of the plurality of modes of operation based upon the value of a selection signal received by the control unit. The line-powered module includes a selection input that is coupled to the control unit such that the selection signal can be received at the selection input. Preferably, the selection input receives a selection wire that can be moved between different points of connection to define the plurality of states of the selection signal. Based upon the connection of the selection wire, the control unit operates the line-powered module in one of the plurality of modes of operation.
