4.2.3 Isolated output IFEED
This output is completely isolated to the electronic circuit of the labeler. Figure 13 shows the
schematic diagram of this isolated output:

4.2.4 Open-Collector-output IFEED
For better resistance against interferences, the Open-Collector-output
IFEED
is also equipped
with a photocoupler. Figure 14 shows the schematic diagram of the Open-Collector-output
IFEED
:

4.2.5 Currentsource-output
For the IR-transmitter of the label scanner
TCY
, a controlled currentsource is used. Figure 15
shows the schematic diagram of the currentsource:
