MB-DS-30 Temperature Transmitter

MB-DS-30 Multi-point Temperature Transmitter, Modbus RTU

Why choose the MB-DS-30?

The MB-DS-30 enables temperature measurement at up to 30 points using external DS18B20 digital sensors operating on the 1-Wire bus. The results are available via RS-485 Modbus RTU.

What does this mean in practice?

• Support for up to 30 measurement points.
• Compatibility with DS18B20 digital temperature sensors.
• The sensor bus operates on the 1-Wire standard.
• The measurement range is −55 to 125°C.
• The current temperature of the connected sensors can be read.
• Measurement and communication parameters are accessible via RS-485 Modbus RTU.
• The dedicated SDS1 probe is sold separately.

MB Config service programme

Service programme for quick configuration of the module’s communication and operating parameters, and for addressing DS sensors.
The programme is available on the device’s subpage or in the DOWNLOADS tab on the website www.fif.com.pl

1-WIRE Standard

The MB-DS-10 utilises a single-channel 1-Wire Master circuit, which enables impedance matching and active ‘intelligent’ pull-up. It enables the construction of small and large 1-Wire networks in serial, hub and star topologies with a length or radius of up to 500 m.
