Driving Multiple Loads
Frequently, several loads in one system are
controlled by several analyzer outputs, whe-
reby the power for the loads derives from a
common source.
Special care is needed when wiring the loads
to minimize interference from switching these
loads:
•
avoid connecting the loads to their power
supply by a common line:
•
It is recommended the loads to be wired
separately, and each load connected se-
parately to the power supply. Beginning
at the distribution point, both the + and
the - wires for each load are laid together
to the load (Fig. 4-31). Interference is
further reduced if a twisted multi-core
cable is used.
