Subject to change without notice WWW.CYLON.COM page 1 of 4 DS0120 rev 24 DESCRIPTION The CBV Series is a freely programmable range of BACnet® Unitary Controllers with native MS/TP communications support. The controllers are BTL listed as BACnet Advanced Application Controllers (B-AAC) and are ideally suited for the control of Variable Air Volume zoning applications. Part of Cylon’s CB Line of BACnet field controllers, the CBV Series features 2 UniPuts™, 4 Universal Inputs and 3 Digital (Triac) Outputs, along with an integrated airflow sensor and a dedicated input for Cylon’s CBT-STAT or UCU Room Display intelligent room sensors. The CBT-2U4-3T model includes an integrated Belimo actuator. The -N variant has a facility for connection to an external actuator. APPLICATION The CBV Series is suitable for controlling single duct or fan assisted Variable Air Volume (VAV) applications. These controllers also support demand ventilation application, occupancy sensing or lighting control to further enhance energy savings. Typical VAV zoning applications include; ▪ Cooling only ▪ Cooling with Reheat ▪ Cooling with Reheat and Perimeter Radiation ▪ Series fan VAV ▪ Parallel fan VAV ▪ Dump box ▪ Room pressurization The controller accommodates available pre-engineered strategies or can be tailored to custom applications using CXpro ᴴᴰ programming software. 2 UniPuts Cylon’s patented technology that can be configured as analog / digital outputs or voltage inputs 4 Universal Inputs Can be configured as analog (voltage or current) or digital inputs 3 Digital (Triac) Outputs Can switch 24 V AC @ 500 mA (live or neutral) BACnet MS/TP Fieldbus Supports the following configurable BACnet objects: AI / BI / AO / BO / AV / BV, Trend Logs, and Schedules Integrated Pressure Sensor 0 … 1.3 inches-water (0 … 320 Pa) Can measure differential pressure directly without need for a separate sensor IntegratedActuator (CBV-2U4-3T) ExternalActuator Port (CBV-2U4-3T-N) Belimo actuator featuring a brushless DC motor with integrated position feedback and 45 inch-pounds (5 N-m) of torque Cylon Intelligent Room Sensor support Up to 500 Strategy Blocks Up to 6 Trendlogs 1024 entries per Trendlog Data Security Strategy and setpoints backed up in Flash No Hardware I/O Jumpers Hardware points are automatically configured by the downloaded strategy ©ABB 2021 All Rights Reserved.
