Temperature converter to connect up to 4 different resistance temperature sensors in dual cable technology with a resolution in 0.1 K. The addressing of the 4 temperature sensors is done via 4 M-Bus addresses according to M-Bus standard DIN EN-1434-3. The temperature is directly converted in the device. The temperature converter occupies 4 clear M-Bus addresses specified by the manufacturer. It is possible to set for each channel 1 of 11 stored temperature sensor characteristics with the M-Bus configuration tool (www.metz-connect.com) or to transmit the resistance value directly. The cable length compensation is done with the push-button assigned to the respective temperature input. The factory setting is: -30 °C to 130 °C / PT1000.
- Connection with spring clamp terminal blocks (push-in)
