Subject to change without notice WWW.CYLON.COM page 1 of 3 DS0133 rev 22 DESCRIPTION The FBVi-2U4-4T is a freely programmable BACnet® Unitary Controller with native BACnet/IP communications support. The controller is BTL listed as BACnet Building Controller (B-BC) and is ideally suited for the control of Variable Air Volume zoning applications. Part of the Cylon® FLXeon Series of BACnet/IP field controllers, the FBVi-2U4-4T features 2 UniPuts™, 4 Universal Inputs and 4 Digital (Triac) Outputs, along with an integrated airflow sensor and a dedicated input for Cylon® room sensors. The FBVi-2U4-4T model includes an integrated Belimo actuator. APPLICATION The FBVi-2U4-4T is suitable for controlling single duct or fan assisted Variable Air Volume (VAV) applications. This controller also supports 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 ABB’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 4 Digital (Triac) Outputs Can switch 24 V AC @ 500 mA (live or neutral) IP Connected Supports the following configurable BACnet objects: AI / BI / AO / BO / AV / BV, Trend Logs, and Schedules Integrated Bi-directional Pressure Sensor 0 … 1.3 inches-water (0 … 320 Pa) Can measure differential pressure directly without need for a separate sensor IntegratedActuator 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 750 Strategy Blocks Up to 15 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 2020 All Rights Reserved.
