Connecting Output Devices
Use
Figure 3.5
to connect your output devices and supply(ies). Two
output commons are associated with each output group:
terminals 6 and 7 for outputs 0 through 3
terminals 14 and 15 for outputs 4 through 7
Terminals 6 and 7 are tied together internally, as are 14 and 15, so that
each output group can use either terminal for that particular group.
