Subject to change without notice WWW.CYLON.COM 1 DS0119 rev 52 DESCRIPTION The CBX Series is a freely programmable range of BACnet® Controllers with native MS/TP communications support. The controllers are BTL listed BACnet Advanced Application Controller (B-AAC) and are ideally suited for a wide range of applications for intelligent control of HVAC equipment, and electrical systems including lighting control and metering applications. The CBX-8R8 and CBX-8R8-H controllers support multi-protocol communications simultaneously including BACnet MS/TP and Modbus® RTU. Part of Cylon’s CB Line of BACnet field controllers, the CBX-8R8 controller features 8 UniPuts™ with Relay, 8 Universal Inputs, as well as support for up to three FLX (Field Level e X pansion) series extension modules providing up to 64 points of control, and a dedicated input for Cylon’s CBT-STAT or UCU Room Display intelligent room sensors. The -H variant provides local override function through HOA switches. FLX I/O expansion modules are available in a variety of options to allow maximum flexibility in achieving the required point configuration. APPLICATION The CBX-8R8 and CBX-8R8-H are designed for a wide range of energy management applications for intelligent control of: • HVAC equipment such as Central Plant, Boilers, Chillers, Cooling Towers, Pump Systems, Air Handling Units (Constant Volume, Variable Air Volume and Multi-zone), and Rooftop Units, • Electrical systems such as lighting control, variable frequency drives and metering. The CBX Series can be used as an integration platform and natively supports the routing of Modbus RTU to BACnet MS/TP without the need for gateways or additional hardware. The controller accommodates available pre-engineered strategies or can be tailored to custom applications using CXpro ᴴᴰ programming software.
