• Remote monitoring and control function

This protection module fulfills two basic functions. Firstly, it distributes the current of a large (non-NEC-Class-2) power source to four 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 as 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 NEC CLASS 2 output channels of the PISA module.  Protection module with one input and four NEC Class 2 outputs Ensures sufficient supply voltage (21V) for critical loads. Protects small cable sizes against overload Integrated control for remote monitoring and operation. Hassle free turn-on of loads with large input capacitors ; Maximum total output current: 20A
