Carrier BN Series Specification

#N2-BN2110-D-4-PB-C – 8/31/23
Overview
The BN Series Temperature and Humidity Duct networked sensors are a cost
effective, single or dual point native BACnet™ or Modbus sensing solution
designed to reduce the need for additional input modules or building management
controllers when a limited number of input points are available. The BN series
offers both BACnet™ and Modbus protocols in one device, providing great
flexibility with various systems. The BTL Certification provides confidence that
these sensors may be used in any new or retrofit installation using a BACnet™
MS/TP controller with third party BACnet™ devices. These sensors incorporate a
conformally coated printed circuit board mounted inside a waterproof enclosure for
long-term reliability. The enclosure features a twist off cover for easy access to the
wiring and internal dip switches for quick setup and installation.
Applications: Monitoring Supply / Discharge / Return Temperature and humidity,
Dehumidification and Humidification Processes, Clean Rooms, Data Centers,
Return Air in Pool Environments, Economizer Control, Air Handlers, Roof Top Units, Process Control Applications
The BN Series BACnet™ sensors are covered by a Two (2) Year Limited Warranty.
