BAScontrol Series Equipped for Wide Temperature Operation
April 2017 - Contemporary Controls' popular BAScontrol Sedona Unitary Controllers are now equipped for wide temperature operation. This upgrade allows the controllers to operate in ambient temperatures between −40°C to +75°C, making them ideal for both indoor and outdoor applications where drastic temperature changes would negatively impact any standard controller. Rugged metal design, low profile, and wide temperature operations make the BAScontrol family an ideal solution for various control, HVAC, and refrigeration applications such as RTU (Roof Top Units), FCU (Fan Coil Units), ERV/HRV (Energy/Heat Recovery Ventilation), WSHP (Water Source Heat Pump AHU), Boiler/Chiller Lead/Lag control, Lead/Lag Water Pump Station with Variable Flow Control, Heatpump AHU, Commercial Dryer Exhaust Booster, as well as Commercial Refrigerant applications.
The BAScontrol Series of controllers supports BACnet/IP and Sedona Framework (SOX) protocols via an Ethernet connection. BACnet MS/TP is supported through a resident EIA-485 port on some models. A real-time clock with a super-cap backup allows for creating local schedules. These controllers are fully web page-configurable using a common web browser, and freely programmable using Sedona's drag-and-drop programming methodology of assembling components onto a wire sheet to create applications.
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 which reside within the device. The controllers can be programmed using Niagara Workbench AX or a third-party Sedona programming tool such as the free Sedona Application Editor (SAE) developed by Contemporary Controls.
All controllers in the series support a common core of features and differ only by I/O count and network connections. Unique to these controllers are 48 web components which link Sedona wire sheet readable/writeable data to web pages, and 24 virtual points which link Sedona wire sheet readable/writeable data to a BACnet client.
"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 Zach Netsov, Product Specialist at Contemporary Controls. "The units are ideal for unitary control or for expanding I/O points in the field via an Ethernet connection."
The BAScontrol20 is a 20-point BACnet/IP, Sedona-programmable unitary controller with direct connection to an Ethernet network. The unit complies with the B-ASC device profile having a convenient mix of 8 universal inputs, 4 binary inputs, 4 analog outputs and 4 relay (20R) or triac (20T) outputs.
The BAScontrol22 is a 22-point BACnet/IP, Sedona-programmable unitary controller with a 2-port Ethernet switch for connection to an Ethernet network. The unit complies with the B-ASC device profile having a convenient mix of 8 universal inputs, 4 binary inputs, 4 analog outputs and 6 relay outputs (no triac model).
