11 Block diagram
The IFC 015 signal converter consists of 3
functional groups.
Functional group 1 contains an input
amplifier, and a high-resolution analog/digital
converter (ADC) that is controlled and
monitored by microprocessor µP 1. At the
same time the processor controls functional
groups 2 and 3. The function values of the
device are stored in EEPROM 1 (ECOPROM),
while all internal correction and calibration
values are stored in EEPROM 2.
Functional group 2 generates a pulsed,
electronically controlled direct current for the
field coils of the primary head. This group is
electrically connected to functional group 3.

Functional group 3 consists of passive FET
optocouplers to allow control of electronic and
electromechanical totalizers. This group is
electrically separated from the other groups.
