Easy World Automation | PULS PISA11.203206 Protection module

PULS PISA11.203206 Protection module

  • Protection module with one input and four 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: 18A


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 current controlled output channels of the PISA module.

You can place an order for the PULS PISA11.203206 Protection module online via one of our Middle East branches (Dubai/ Oman/Saudi Arabia) and get it delivered at a low cost at a specific time.
