9.3 Connection variants

The signal converter is a 4-wire device with 4...20 mA current output and HART
Depending on the version, the settings and the wiring, the current output can operate as passive
or active output.
• Multi-drop mode is supported Multi-drop mode is supported Multi-drop mode is supported Multi-drop mode is supported
In a multi-drop communication system, more than 2 devices are connected to a common
transmission cable.
• Burst mode is not supported Burst mode is not supported
Burst mode is not supported Burst mode is not supported
In the Burst mode a slave device transfers cyclic pre-defined response telegrams, to get a
higher rate of data transfer.
INFORMATION!
For detailed information about the electrical connection of the signal converter for HART
to the section "Electrical connection".
There are two ways of using the HART
• as Point-to-Point connection and
• as multi-drop connection, with 2-wire connection or
