Pulse Test Sources
There are two digital pulse test sources (PO) used for line control
monitoring of digital inputs. For information on configuring pulse test
sources for line control, see
.
Pulse test sources are connected to these terminals.
TIP
Inductive loads can be connected without a protection diode on
the load. However, Rockwell Automation strongly recommends
that a protection diode be fitted directly to the load to suppress
any interference voltage.
