Logic Structure
7.8.1 Combined AND/OR Logic Term
Relays can be connected to form various logic structures. The following example shows a combination of AND
and OR terms.
Figure 7-21 More complex logic structure
The logic term represented by this structure would be:
Out1 = (1 and 2 or 3 and 4) and 5 and 6 and (7 and 9 or 8 and 10)
Figure 7-22 Equivalent logic gate for figure 14
Note
The logic above depicts the equivalent logic equation for
interlock logic condition, not the actual TTL gate level for timing
analysis purposes.
