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 (see Fig. 3).
Set the selector switch, S1 to SRC. The switch must be rated for at least 20 mA at 20 VDC.
