Transmitter supply
The DC 24 V transmitter supply is available at terminals 13 and 14. The
transmitter supply is galvanic insulated from the measuring input. Current
loop sensors (2-wire) and 3-wire and 4-wire sensors can be operated via the
transmitter supply as long as their current consumption is not higher than 50
mA (Power consumption < 1.2 VA).

6.2.2 Connection Examples
This section gives a few examples of practical connections.
a) 4…20 mA signal, 2-wire-transmitter
b) 0…20 mA signal, 3-wire-transmitter
The voltage drop on the transmitter supply wire is irrelevant, which is
why this can also be bridged directly on the indicator.
