For a functioning HART communication in the output circuit a load resistance
of at least 250 Ω is necessary (e.g. input resistance of the input sub-assem
-
bly). If not available, the internal 221 Ω resistor can be used additionally.
In this case, the connection must be made to the terminals "3+/2-" or "4+/6-".
The maximum output load is reduced to 479 Ω. For variants 9160/19-11-11
and 9160/19-10-10 a HART communication is supported on channel 1 only.
