Chapter 4 Safety Function
Figure 25 - Nomenclature for Cascaded Design
Nomenclature that is used for a cascaded design (example for a cascaded
system with three cascaded pairs).
The first pair in a cascaded system is called the host pair. The OSSD outputs of
the host pair are connected to safety contactors, a safety relay, or a safety PLC.
Cascading allows the 450L-E or 450L PAC safety light curtain to help protect
multiple sides of a machine and to connect the complete design with only two
OSSD safety outputs to the machine safety control.
See
Cascading Application on page 183
for a typical application with cascading.
