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

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 NEC CLASS 2 output channels

of the PISA module.
