  • Network Communications for Buildings
    Network Communications for Buildings 2015 About Contemporary Controls Contemporary Controls serves the building automation industry with products based upon open standards such as BACnet, Modbus and Ethernet. Our customers are systems integrators, contractors, mechanical and controls OEMs seeking simple and reliable networking and control products from a dependable source. 2010 BASautomation®– Building on BACnet provides routing, gateway and control solutions compatible with an internationally recognized building automation standard. CTRLink® – Ethernet Built for Buildings consists of unmanaged and managed switches, media converters, and wired and wireless IP routers. These products are designed for unattended operation in environments not conducive to office grade equipment. 2005 With headquarters based in the US, we have operations in the UK, Germany and China with self- manufacturing in the US and China. Celebrating 40 Years! George Thomas established Contemporary Controls in 1975 as a system integration and consulting business focusing on microcomputer and PLC applications. As 2000 microprocessor bus-boards became more popular, in 1983 the company changed direction to become a hardware manufacturer by developing a series of STD- BUS microcomputer modules and became active in the STD-BUS Manufacturers' Group (STDMG). One of those modules developed was an ARCNET® adapter. As ARCNET acceptance increased, Contemporary 1995 Controls was the catalyst for creating the ARCNET Trade Association (ATA) in 1987 to better publicize this technology to the automation world. With most of the major building automation companies using ARCNET, Contemporary Controls became a supplier to all the OEMs that incorporated ARCNET in their systems.
