Remote Operation Instructions IFC090 HART
1 General Information
The IFC090 is a two-wire transmitter with 4...20mA current output and HART capability. Dependent on device
implementation it is available with active current output (‘Standard + HART’, ‘Modis-3’) or passive current output
(‘Standard + HART’, ‘Modis -1 ’, ‘Mo d is- 2’) .
General Characteristics of the IFC090 HART interface:
•
Multidrop Mode is supported
•
Burst Mode is not supported
Electrical connection: Refer to sections 2.1, 2.2, 2.6 of the “Installation and Operating Instructions Electromagnetic
flowmeters IFC 090 K/F” (KROHNE) – for ‘Standard + HART’ device implementation, and to sections 4-6 of the
“Information about IFC 090i (Modis-devices)” (KROHNE) – for ‘Modis’ instrument implementations.
There are two ways of using the HART communication:
a) As a point-to-point connection between the IFC090 and the HART master equipment. The instrument may be
equipped with either active or pass ive curr ent out put ( ‘Modis ’) or be conf igure d with des ir ed current output (‘Standard
+ HART’).

b) As a multipoint connection (multidrop) with up to 15 devices (IFC090 or other HART equipment) in parallel. The
instruments must be equipped (or configured) with passive current output.
