Abstract
A building automation system is disclosed which enables reliable operation and cost effective expansion. The system utilizes pairs of complementary modules, one of which is a primary module that is installed at a main cabinet and the other is an expansion module that can be located adjacent the mechanical systems which are to be monitored and controlled. Through the use of the complementary pairs of modules, the necessity for providing home runs of power conductors from the mechanical system to the main cabinet are substantially reduced if not eliminated, which greatly reduces the costs of materials and labor in a total installation.
