PULS PISA11.403 Protection Module

Introduction

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 uninterrupted supply voltage for sensitive equipment, 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 by 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 current-controlled output channels of the PISA module.
