Digital Outputs
Digital outputs are used to turn on or turn off external devices.
Digital outputs are CMOS compatible and operate between 0Vdc
and +5Vdc. Outputs can be used to control solid state output
modules, CMOS and TTL logic circuits. Caution must be taken not
to exceed the power capability of the outputs. Refer to the output
specifications in Chapter 1.
Setting an output line to a "1" forces the output HIGH, and setting
an output line to a "0" forces the output LOW.
Figures 4.5 - 4.6 show examples of some typical output
interfaces.
