1 The CBXi Series
INTRODUCTION
The CBXi-8R8 and CBXi-8R8-H are fully programmable IP-based BTL-listed BACnet® Building Controllers
(B-BC) that supports simultaneous multi-protocol communications including BACnet/IP, BACnet MS/TP,
Modbus TCP, and Modbus RTU.
Part of Cylon’s CB Line of BACnet field controllers, the CBXi Series of controllers are built on an extendible
platform that features 8 UniPuts™ with Relay and 8 Universal Inputs, and feature support for up to five
FLX (Field Level e
X
pansion) Series extension modules providing a scalable solution from 16 up to 96
points of control. FLX expansion modules are available in a variety of options to allow maximum
flexibility in achieving the required point configuration. The CBXi-8R8-H provides local Hand-Off-Auto
override functionality.
The fully programmable CBXi-8R8(-H) can be tailored to meet a variety of applications by creating and
modifying strategies using Cylon's CXproᴴᴰ programming interface.
APPLICATION
The CBXi-8R8(-H) is 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 CBXi-8R8(-H) can be used as an integration platform and natively supports the routing of either
BACnet MS/TP to BACnet/IP or Modbus RTU to Modbus TCP without the need for gateways or additional
hardware.
