The following recommendations apply for all signal connections to your
board:
•
Separate board signal lines from high-current or high-voltage lines.
These lines can induce currents in or voltages on the board signal lines
if they run in parallel paths at a close distance. To reduce the magnetic
coupling between lines, separate them by a reasonable distance if they
run in parallel, or run the lines at right angles to each other.
•
Do not run signal lines through conduits that also contain power lines.
•
Protect signal lines from magnetic fields caused by electric motors,
welding equipment, breakers, or transformers by running them through
special metal conduits.
For more information, refer to the application note, Field Wiring and Noise
Consideration for Analog Signals, available from National Instruments.
