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’, ‘Modis-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 passive current output (‘Modis’) or be configured with desired 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.
