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

four
