Contact-Sensing Inputs
Contact-sensing turn-on voltages and burdens are listed in Table 1-2. Burden values assume nominal
value of input voltage applied.

NOTE
All timing specifications are for the worst-case response. This includes output
contact operate times and standard BESTlogic operation timing but excludes
input debounce timing and non-standard logic configurations. If a non-standard
logic scheme involves feedback, then one or more BESTlogic update rate delays
must be included to calculate the worst-case delay. An example of feedback is
Virtual Outputs driving Function Block Inputs. For more information, see Section
7, BESTlogic Programmable Logic.
