Supplementary Installation and Operating Instructions UFC 030 HART
HC275, FC375, AMS, PDM
1 General Information
The UFC 030 is a “four-wire” transmitter with 4...20mA current output and HART  capability. Dependent on device
implementation it is available with active/passive current output (standard) or passive current output (MODIS).
General Characteristics of the UFC 030 HART
 interface:
• Multidrop Mode is supported
• Burst Mode is not supported
Electrical connection: Refer to section “Electrical connection of the signal inputs and outputs” of the following manual:
• “Installation and Operating Instructions Universal 3-Beam ultrasonic flowmeter UFM 3030 Compact
ultrasonic flowmeter UFC 030 Ultrasonic flow converter UFS 3000 Ultrasonic flow sensor” (KROHNE)
There are two ways of using the HART
 communication:
a) As a point-to-point connection between the UFC 030 and the HART
 master equipment. The instrument's current
output may be active or passive.
