New BACnet/IP Sedona Field Controller on Display at AHR Expo Booth #239

January 2014 - Contemporary Controls new BAScontrol20 Sedona Controller will be featured at next week's 2014 AHR Expo. The BAScontrol20, a 20-point BACnet/IP Sedona Field Controller that includes a Sedona virtual machine, is an example of how we take our customers' product needs into consideration regarding our continued development of IP-based controls.

Ideally suited for structured wiring systems, the BAScontrol20 is BACnet/IP compliant with a B-ASC device profile. Having a resident Sedona Virtual Machine (SVM), the unit is freely programmable using either Niagara Workbench or Sedona Workbench. For remote Ethernet I/O applications, the unit can be configured with minimal effort using a web browser. The BAScontrol20 provides a convenient mix of eight universal inputs, four binary inputs, four binary outputs as well as four analog outputs. Models exist for both triac and relay outputs. The unit is ideal for expanding I/O points in the field via an Ethernet connection.

"The BAScontrol20 has eight virtual points that can be used by BACnet clients to read/write values to a Sedona wire sheet, for example writing set points or reading status," says Bennet Levine, Contemporary Controls R & D Manager. "In addition, the BAScontrol20 has 48 web components that allow the viewing or writing of 48 values used on the Sedona wire sheet from a web browser."

• The BAScontrol20 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, the BAScontrol20 can share the same Ethernet network with supervisory controllers and operator workstations.
• The 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 and NTP support allows for creating local schedules. The real-time clock supports daylight savings time.
• A 10/100 Mbps Ethernet port supports protocols such as BACnet/IP, Sedona SOX, HTTP and FTP.
• Configuration of universal inputs and pulse inputs can be accomplished using a web browser.
• The BAScontrol20's four pulse inputs operate up to 40Hz and can accommodate 0-10V or contact closure pulse sources
• Type II and type III 10k thermistors curves are resident in the unit.
• Current inputs can be measured using external resistors.
• Contact closures require a voltage-free source.
• Binary outputs and analog outputs require no configuration.
• The unit is powered from either a 24VAC/VDC source.

The BAScontrol20 is in our BASautomation-Building on BACnet product family and is a BACnet compliant device.
