GENERAL DESCRIPTION

SHORT-FORM DATA

This protection module fulfills two basic functions. First it
distributes the current of a large power source to four lower
current output channels and therefore allows for smaller
wires to be used. The second function is to permit only so
much current on the outputs that the input voltage of this
unit (which corresponds to the output voltage of the power
supply) does not fall below 21V.

This ensures a safe and an uninterrupted supply voltage for
sensitive equipments, such as PLCs, controls or sensors, when
they are connected directly to the same power supply as the
PISA module. Less critical loads that are not affected to short
voltage interruptions or that could even be the cause of a
fault on the 24V power supply are connected to one of the
