The BN Series Outdoor Temperature and Humidity 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.
