Connecting BAS Devices to an IP Infrastructure

Contemporary Controls has been supporting building automation OEMs' ARCNET and Ethernet products for years by addressing the unique needs of this industry. The industry is embracing Ethernet connectivity to Direct Digital Controllers (DDC) along with open protocols such as BACnet, Modbus and Sedona Framework. Contemporary Controls' BAS Remote supports all these protocols while providing universal input/output connections to temperature sensors, damper actuators, as well as other common HVAC devices. Besides standard ARCNET hubs and Ethernet switches, the company provides protocol-aware routers and gateways unique to the building automation industry.

The BAS Remote provides a convenient method of expanding building automation systems in the field when using Ethernet for network communication. In addition to universal I/O points, the unit functions as BACnet/IP and Modbus TCP remote I/O, a Modbus Serial to BACnet gateway, and a Powered by Sedona Framework controller.

The BAS Router is used to route messages between BACnet/IP, BACnet Ethernet and BACnet MS/TP networks. Two versions are available – a DIN-rail mounted unit for fixed installations and a portable unit for commissioning and troubleshooting.
