KROHNE IFC 300 Converter HART 0201 - Manual (Page 3)

Supplementary Handbook IFC 300 HART, FC375, AMS, PDM, DTM
1 General Information
The IFC 300 is a “four-wire” transmitter with 4...20mA current output and HART
® capability. Dependent on
jumper setting and/or wiring the current output can operate as active or passive output.
General characteristics of the IFC 300 HART
® interface:
• Multidrop Mode is supported
• Burst Mode is not supported
Electrical connection: Refer to section “Electrical connection: outputs and inputs” of the following manual:
• “Handbook IFC 300 signal converter” (KROHNE)
There are two ways of using the HART
® communication:
a) As a point-to-point connection between the IFC 300 and the HART master equipment. The instrument's
current output may be active or passive.
