Johnson Controls NSB8BHN240-0 Sensor

The Johnson Controls NSB8BHN240-0 is a commercial-grade NS8000 series network sensor designed for precise climate monitoring in building automation systems. This unit integrates high-accuracy temperature and relative humidity (3% RH) sensing into a single, surface-mounted device. Built for seamless integration with Metasys and Facility Explorer BACnet MS/TP field controllers, it facilitates reliable communication via the Sensor Actuator (SA) Bus. The fixed segment LCD allows for immediate on-site verification of zone conditions, featuring a white digital display with logo for a clean, professional finish.

As a veteran technician, you will appreciate its rugged plastic enclosure and straightforward screw terminal or modular jack terminations, ensuring efficient installation in new builds or retrofits. The NSB8BHN240-0 is an engineered replacement for several legacy models, including the NS-BHR7101-0, NS-BHB7002-0, NS-BHR7103-0, and NS-BHB7001-0. It operates on a nominal 15 VDC supply and provides a robust temperature measurement range from -40 to 158°F, making it a critical component for maintaining strict environmental parameters in demanding HVACR applications.

• Multi-Protocol Compatibility: Fully compatible with Johnson Controls Smart Equipment, Verasys, and Metasys SA Bus networks for simplified commissioning.
• Precision Sensing: Utilizes thin film capacitive humidity sensor technology for stable, long-term 3% RH accuracy and digital temperature sensing.
• Streamlined Installation: Features a modular jack and screw terminal interface to accommodate various field wiring preferences.
• Legacy Integration: Designed as a direct drop-in replacement for obsolete NS-BHB and NS-BHR series sensors, reducing downtime during system upgrades.
• Enhanced Monitoring: Fixed segment display provides absolute setpoint adjustment and clearer visibility of zone humidity and temperature data.

Is the NSB8BHN240-0 compatible with third-party BACnet systems?
While optimized for Johnson Controls Metasys and Facility Explorer, this sensor communicates using the standard BACnet MS/TP protocol, allowing it to interface with compatible building automation controllers that support SA Bus integration.

Can this sensor replace an older NS-BHR7101-0 unit without rewiring?
Yes, the NSB8BHN240-0 is the direct technician-recommended replacement for legacy models like the NS-BHR7101-0 and NS-BHB7001-0, typically utilizing existing wiring and mounting footprints.

Does this model include a CO2 or Occupancy (PIR) sensor?
No, the NSB8BHN240-0 is a dedicated temperature and humidity model. If CO2 or PIR functionality is required, a different model within the NS8000 series must be selected.
