Power pack for supplying power to 2-wire measuring transducers with DC auxiliary power, and for 1:1 transmission of the measuring signal, electrically isolated from the measurement output.

Conversion to another signal range is also possible, for example 0 to 5 mA or 1 to 5 V (signal converter).

Certain variants of the B811 are FSK compatible (frequency shift keying). They are used for dialog-capable "intelligent" measuring transducers with FSK technology and HART or a company-specific protocol.
