Product Details
Instrument Introduction:
DW485N-BThe series of products adopt Swiss high-precision temperature and humidity probes with RS485 data output interface and two-way control output. They use the widely used MODBUS protocol in the industrial field to achieve long-distance transmission and multi-point simultaneous detection. It has the characteristics of accurate measurement, stable operation, and long service life. It is a good choice for networked centralized monitoring of temperature and humidity
Instrument features:
- standardRS485Output communication interface, widely used in the industrial fieldMODBUSProtocol, other protocols can be customized
- Full process digital high-precision probe
- Economical, universal, high-precision, meeting different precision requirements
- It has been calibrated at the factory and does not require recalibration
- Excellent long-term stability
- low power consumption
- Easy to install
- Good scalability
- Super strong human-machine interface software support, displaying all current temperature, over limit alarm and other information through the human-machine monitoring interface. There is also historical data analysis function, and tables and curves can be printed
- Two relay control outputs, one for temperature/humidity
- Two way switch input detection
