Sinking Logic
When the parameter is
programmed to Low, check
with device GUI option. The
user inputs of the controller
are internally pulled up to
+3.3 V with 20 KΩ
resistance. The input is
active when it is pulled low
(<0.9 V).
Sourcing Logic
When the parameter is
programmed to High, check
with device GUI option. The
user inputs of the controller
are internally pulled down to
0 V with 20 KΩ resistance.
The input is active when a
