January 2016 - Contemporary Controls' newly released BAScontrol22 Sedona Unitary Controller joins our popular BAScontrol Series which supports both BACnet/IP and Sedona Framework (SOX) protocols via an Ethernet connection. The BAScontrol22 has two additional relay outputs to support multi-stage rooftop units. Using a built-in Ethernet switch with two external ports, controllers can have daisy-chained network connections. A resident web server allows the controllers to be accessible via a common web browser. Controllers in the series support a common core of features and differ only by I/O count and network connections. A video introduction is available for both the BAScontrol20 and the new BAScontrol22.
"Because it's both BACnet/IP compliant and has a direct connection to an Ethernet network, the BAScontrol Series is an easy solution that demonstrates the value of open systems by reading and writing BACnet points over an IP network," said Joe Stasiek, Sales Manager at Contemporary Controls. "The units are ideal for unitary control or for expanding I/O points in the field via an Ethernet connection."
Each device in the series is a freely-programmable controller executing Sedona's drag-and-drop methodology of assembling components onto a wire sheet to create applications. They can be programmed using Niagara Workbench or a Sedona programming tool such as Contemporary Controls' Sedona Application Editor (SAE). Built on the Sedona Framework, Contemporary Controls has developed more than 100 custom Sedona components which complement the standard Tridium-developed Sedona 1.2 components that reside within the device. Unique to the BAScontrol Series are 48 Web Components that allow wire sheet data to be read and written from a common web browser; and 24 Virtual Components that allow wire sheet data to be read and written from a BACnet client.
The BAScontrol Series is comprised of the BAScontrol20 with 20 points of I/O and the BAScontrol22 with 22 points of I/O. The BAScontrol20 has a single Ethernet port while the BAScontrol22 has a built-in Ethernet switch with two external ports. Each controller utilizes a powerful 32-bit ARM7 processor with 512 kB of flash memory plus a 16 Mbit serial flash file system for storing configuration data and an application program. By operating at the BACnet/IP level, each controller can share the same Ethernet network with supervisory controllers and operator workstations. Each unit can be configured for a fixed IP address or can operate as a DHCP client receiving its IP address from a DHCP server. A real-time clock with a super-cap backup allows for creating local schedules.
