GENERAL DESCRIPTION
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
