6.4.3. Limiting through currents
Inside E20-10 circuits AGND, GND, GND*, presenting on module connectors are
interlinked (p. 6.5.3) . This places certain restrictions on maximum permissible through currents
through circuits AGND-GND-GND*.
Attention! Maximum permissible through currents exceeding can cause E20-10 failure .
Table6-5. Maximum permissible through currents
Circuit Maximum allowable output current
AGND-GND
0.1 А
AGND-GND*
0.1 А
GND-GND*
0.7 А
6.4.4. External power supply input characteristic
When
E20-10
is energized not from AD adapter including in delivery package (p. 3.3.1 ) and
from external direct current source the following parameters shall be taken into account:
