PULS DIMENSION PISA11 4-Output DIN Rail Protection Modules - 24V DC 4-20A

These protection modules from PULS fulfill two basic functions. First they distribute 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 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.
