Outputs
Digital outputs are used to turn "ON" or turn "OFF" external
devices. Outputs can be used to control solid state output modules,
logic circuits, and relays. Caution must be taken not to exceed the
power capability of the outputs. Refer to the DBM16 output
specifications.
Setting the SDD16 module's output line to a "1" turns "ON" the
DBM16's output line. Setting the SDD16 module's output line to a
"0" turns "OFF" the DBM16's output driver. The DBM16 outputs are
open collector current sinking drivers. Figures C.7 - C.9 show
examples of some typical output interfaces.
