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 the ONICON Technical Department if you are uncer
tain as to the proper jumper selection.
