AC voltage ranges are calculated using the default recognition time (4 ms) and debounce time (16 ms).

† Voltage ranges depend on jumper configurations. See Section 3, Input and Output Functions, Contact-

Sensing Inputs.

Input Burden

Burden values shown in Table 1-2 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.
