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

3 Current output

• galvanically isolated from all other groups
• converts the digital output signal from the

µ

P 3 microprocessor into a proportional current

4 Binary outputs

• galvanically isolated from other groups
• selectable input/output combinations
• pulse output (P), passive FET optocouplers allow connection

of electronic and electromechanical totalizers

• status output (S), for limit value, error identification, or flow direction

in forward/reverse flow mode (F/R)

5 Display/operator control unit (option, D Version)

• large-size illuminated LC display
• 3 keys for operator control of the signal converter
• connection to the internal IMoCom bus
• unit can be retrofitted to basic devices (B Version)

6 IMoCom bus plug connector

for connection of external control and test devices such as:

• HHT handheld terminal (option), display/operator control unit for operation of basic versions
• adapter and CONFIG software for operation via MS-DOS PC
