• It‘s better to apply "parallel" wiring at
which each single load is supplied by a
separate connection starting from a
distribution point: Both "+" and "-" wire of
any load are run together, starting at the
point of distribution and ending at the load
(see fig. 4-30). The effect of minimizing
disturbances is intensified when using
twisted pair cables.
Point of distribution
Run wires for one load
in parallel as long as
even practicable
(drill if possible)

4-5-4 Driving High Current Loads
Loads with currents exceeding the rated
currents specified for X-STREAM series
analyzers outputs (>30 mA / > 1 A) must not
be driven directly by digital or relay outputs.
Driving such loads requires external relays
acting as decoupling devices: The X-
STREAM output drives the external relay, which
itself drives the load.
It is recommended to use separate supplies
for analyzer and high current loads to minimize
interferences (fig. 4-31).
As described before using suppressor diodes
for inductive loads is strongly recommended!
