Powered Pulse:
This type of output refers to a pulse which has an associated voltage with it (see fig. 2).
set the selector switch, s1 to Pwrd Pulse. The allowable voltage range is 5-24 VDC. The
input impedance is set at the factory to be 11 kOhM via the impedance selector jumper
(J1, see fig. 1). a lower impedance, 3 kOhM can be selected if required by the instrument
providing the pulse output. Consult the instrument manufacturer or ONICON if you are
uncertain as to the proper jumper selection.

Open Collector (Sourcing):
This type of output refers to an open Collector switch configured for a sourcing function
