Sample rate (sampling mode)
1
–
50 samples per second (applies to all 6 inputs).
Sample rate is user
-
selectable. A value of
0 selects
edge

detection mode.
Debounce Count
(sampling mode)
Number of samples needed to declare an input valid.
This is use
r
-
selectable and each input is
independently
configurable. For instance if the sample rate is 4 samples per second, and the
debounce value is set to 20, then the signal must be in the same state for 20 consecutive
s
amples to be declared
valid, which woul
d be for a period of 5 seconds. Debounce values are
ignored in edge

Pin MTA
with
2.54 mm (0.1”) spacing. Recommended mating connector is AMP 641190

2.
Recommended Input
Cable
Alpha 6300/4, Belden 9534, or equivalent having less than 100pF/ft capacitance. This
cable
type is 24awg, shielded, and has a PVC jacket.
Terminate only one end of the cable shield to
signal common or ground.
Maximum cable length run should not exceed 1000 feet. Other
cable types or gauges can be also be used as long as careful considera
tion is given to suitable
wiring practices and performance.
