Connecting the Relays
The FX15 controller features up to nine Digital Outputs with
electromechanical relays. To simplify assembly, the common terminals
of some relays have been grouped together. The relays are divided into
six groups, according to the distance of insulation.

Figure 40: Relay Groups
Inside each group the relays have single isolation only and must be
connected to the same voltage supply. Between the groups there is
double isolation, and the groups can be connected to different voltage
supplies.
Figure 41 displays a typical application of the relay outputs as a
connection example.
