FIGURE 20: RELAYS OUTPUTS GROUPS A, B AND C BLOCK DIAGRAM
There are three groups of two relays, called A1 and A2, B1 and B2, C1 and C2, each group with its
own common terminal (A, B and C).
This allows to connect external loads supplied by three different sources, making the cabling of the
whole system very easier.
