Digital Outputs

Digital outputs are used to turn external devices on or off. Digital

outputs are CMOS/TTL 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.
