Digital outputs:
Modules should never be installed or removed while power is applied to the I/O Plexer
Repeater.
ODC5, ODC5A, OAC5, and OAC5A digital output modules are used to switch external
power supply loads on and off.
Because they contain a protective reverse diode, the ODC5 and ODC5A output modules are
polarity sensitive and operate correctly only when the “=” terminal is more positive than the
“-“ terminal. A DC digital output module connected backwards conducts current through its
protective diode and appears to be uncontrollable, it is. Polarity does not affect the
performance of OAC5 and OAC5A digital output modules.
Because the field sides of output modules are totally isolated from each other, like polarities
can be wired common to make use of a single power supply.
It should be noted that the status indicator only follows the logic instruction to the modules
and does not show that the module, its fuse, or external power is present. Outputs can only be
truly verified by monitoring the output with a multimeter, oscilloscope, or by employing a
digital input module as a feedback tool.
