MODULAR AND EXPANDABLE IRRIGATION CONTROLLER

摘要

The irrigation controllers are modular in that various functional components of the irrigation controller are implemented in removable modules (55, 65) that when inserted into position within the controller housing (40), expand the capabilities of the controller. Also described are various different typ es of expansion modules (65) that may be coupled to the modular controller, having as variety of functions and features, as well as related methods of u se and configuration of these modules in the controller.
