ENERAL ESCRIPTION
This protection module fulfills two basic functions. First 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 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
DC 24V
Power
directly to the
Supply
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 NEC CLASS 2 output channels
of the PISA module.
