DDC-Online provides unbiased information on Direct Digital Controls (DDC) and an easy searchable guide to DDC manufacturers. The Reliable Controls MACH-System™ has now been included in DDC-Online's Manufacturers Product Listing.

Due to the complexity and proprietary nature of DDC systems, it has become difficult to stay current with the designs, installations, operation and maintenance of DDC systems. DDC-Online was developed specifically to help building owners and consulting/specifying engineers with these issues.

Both generic and specific information on DDC systems can be found including:

• basic introduction to DDC and the terms used in the industry
• detailed listing of DDC system architectures, hardware components and software associated with DDC systems from the prominent national manufacturers
• detailed publication on input and output processes of DDC systems.

A generic framework of the various components and configurations used in current DDC systems has been defined. This framework provides information on DDC manufacturers in a consistent format so readers can easily compare their relative features and benefits.

The Iowa Energy Center developed this web site in conjunction with the U.S. Department of Energy Office of Building Technology, State and Community Programs (DOE-OBT), Pacific Northwest National Laboratory (PNNL) and Facility Dynamics Engineering.

The Reliable Controls listing provides building automation specialists a source for comparing the Reliable Controls MACH-System™ to other manufacture specific data on DDC systems. Reliable Controls is committed to quality technology, excellent technical support and innovative products.
