This protection module fulfills 2 basic functions. First it distributes the current of a large (non NEC Class 2) power source to 4 NEC CLASS 2 output channels and therefore allows for a simpler wiring method and easier approval process of the entire machine. 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 1 of the 4 NEC CLASS 2 output channels of the PISA module.
