Cascading
Example:
Delay between input I0 - cascading
output Unit 1: 40 ms
Delay between input I0 - cascading
output Unit 2: 40 ms + 40 ms
Delay between input I0 - semiconductor
output Unit 3: 40 ms + 40 ms
+ 40 ms
Delay between input I0 - relay output
Unit 4: 40 ms + 40 ms + 40 ms
+ 60 ms

Incorporating PNOZelog units:
PNOZelog units may also be included
in the series connection. The delay
times on the individual units are
also added together with this type
of cascading.
Remember to consider the switchon
delay and any potential delay
time for the outputs on the
PNOZelog units (see operating
manual or PNOZelog technical catalogue).
When connecting PNOZmulti -
PNOZelog, the cascading output
“CO-” is not connected.
