CBX System

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

programming interface.
