Driving Multiple Loads

Frequently, several loads in one system
are controlled by several analyzer outputs,
whereby 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 in series:
It is recommended to wire the loads in
•
parallel, and to separately connect each
load to the power supply: Beginning at the
distribution point, lay both the + and the
- wires for each load together to the load
(Fig. 2-21). Interference is further re-
duced if a twisted multi-core cable is
used.
