DESCRIPTION
The CBX-8R8(-H) is a fully programmable BTL-listed BACnet®
Advanced Application Controller (B-AAC) that communicates on
an RS-485 local area network using the BACnet® MS/TP protocol.
This controller features 8 UniPuts™ with Relay and 8 Universal
Inputs as well as support for up to three FLX (Field Level
eXpansion) series extension modules providing up to 64 points
of control. FLX expansion modules are available in a variety of
options to allow maximum flexibility in achieving the required
point configuration.
The CBX-8R8(-H) is designed for a wide range of applications for
intelligent control of HVAC equipment, lighting control, and
electrical systems including metering applications.
APPLICATION
The CBX-8R8(-H) is suitable for controlling various equipment
such as; air handling units, boilers, chillers, cooling towers, pump
systems, central plant equipment, variable frequency drives,
lighting control and metering. The controller supports multi-
protocol communications simultaneously including BACnet®
MS/TP and Modbus® RTU.
The fully programmable CBX-8R8(-H) can be tailored to meet a
variety of applications by creating and modifying strategies using
Cylon's CXpro
HD
programming interface.
