MB-DS-2 2-channel temperature transducer, Modbus RTU
Why choose the MB-DS-2?
The MB-DS-2 enables independent temperature measurement at two points using external DS1820 or DS18B20 digital sensors, and transmits the results via RS-485 Modbus RTU.
What does this mean in practice?
- There are 2 independent temperature measurement channels available.
- Each channel works with an external DS1820 or DS18B20 digital sensor.
- The measurement range is −55 to 125°C.
- In addition to the current temperature, the recorded minimum and maximum values can be read.
- It is possible to set the averaging time for the result.
- Calibration correction is available.
- Communication takes place via RS-485 Modbus RTU.
Important: the dedicated SDS1 probe is available separately.
MB Config
The software allows you to test-read values and configure the transmitter’s communication and configuration parameters.
Communication between the module and a PC is via theCN-USB-485 USB converter.
The software is free of charge.
