Pulse Test Sources
The 1753-IB16 input module is equipped with four pulse test sources
that can be software-configured for pulse testing of safety inputs, if
required. Due to minimal current capacity, these pulse test sources
cannot be used as outputs if they are not configured as pulse test
sources.
For information on configuring pulse test sources for line control, see
for example wiring diagrams.
Pulse test sources are connected to these terminals.
ATTENTION
Pulse test sources must not be used as safety-related outputs.
