The NSB8MHC240-0 from Johnson Controls serves as an advanced network wall sensor that measures crucial environmental factors. Weighing only 0.4 lbs, it has an operational supply voltage varying between 9.8 and 16.5 VDC, with a nominal value of 15 VDC drawn from the SA Bus.The sensor can accurately measure temperatures ranging from 0 to 40 °C. Additionally, it can detect CO2 concentrations up to 2000 ppm.
For humidity detection, it employs a thin film capacitive type sensor. A built-in PIR (Passive Infrared) sensor enhances functionality by detecting occupancy for better energy efficiency in managed spaces. The unit's display is a fixed segment LCD, enabling users to easily view the current measurements.
This sensor is housed in a white enclosure, maintaining a professional appearance suitable for various installations. Regarding environmental resilience, it can operate at minimum and maximum temperatures ranging from 0 °C to 50 °C, with a broader storage temperature capability spanning from -40 °C to 50 °C.
The setpoint adjustment range, crucial for maintaining desired conditions, varies from 10 °C to 30 °C, providing flexibility for user-specific applications. The NSB8MHC240-0 integrates effectively into existing systems, greatly benefiting climate control and monitoring in residential and commercial environments.
