Installation and operating instructions

IFC 020

12/1

12 Block diagram – signal converter

1 Input amplifier

overdrive-proof signal processing,

rapid and accurate

digital signal processing and sequence

control

patented, high-resolution A/D converter,

digitally controlled and monitored

high signal-to-noise ratio through low-

loss field power supply

2 Field power supply

the low-loss field power supply

generates the pulsed, electronically

controlled DC current for the magnetic

coils of the primary head

the low-loss regulator reduces the power

take-off

high field current causes a high signal

level.

3 Current output

galvanically isolated from all other

groups

converts the digital output signal from the

P 3 microprocessor into a proportional

current

HART

and RS 485-interfaces,

switchable

4 Binary outputs

galvanically isolated from other groups

selectable input/output combinations

pulse output, passive FET optocouplers

allow connection

of electronic and electromechanical

totalizers

status output, for limit value, error

identification, or flow direction

in forward/reverse flow mode (F/R)

5 Display/operator control unit

large-size illuminated LC display

3 keys for operator control of the signal

converter

connection to the internal IMoCom bus

6 IMoCom bus plug connector

for connection of external control and

test devices

7 External control input

(IFC 020 E only)

reset of internal totalizer

zero setting of all outputs

The standard

high accuracy

practice oriented standard equipment

current and pule output (galvanically

isolated)

status output, adjustable for many tasks:

indicators for trip point, flow direction and

errors.

IMoCom-Bus suitable for many in- and

external tasks

simple, uniform KROHNE control outline

very lowpower consumption

HART

and RS 485-interfaces
