Honeywell Excel Family of Controllers

The Excel 500 and 100 are DDC controllers that are programmed using the Excel CARE graphic programming tool and offer modular inputs and outputs that can be easily added to expand the controller point capacity.

An Excel 500 controller can include up to 18 plug-in modules including a CPU module, power supply module, and user-selectable combination of analog and digital input and application expansion.  It is a building block of construction with a variety of modules to meet the customer's control systems needs.  The controller can be used as a stand-alone or integrated system on the peer to peer C-bus network.  The network can link up to thirty controllers on the bus, with each controller providing up to 128 physical points.
