Mode “SE 1” uses INPUT1 to select between two current values. When
INPUT1 changes state the output current changes. Mode “SE 2” uses INPUT2
to select between two output currents. Mode “SE12” uses the four
combinations of INPUT1 and INPUT2 to select between four different output
currents.

Pulsed Output
The output is off by default. When a trigger is received on one of the digital
inputs, the PP600 will wait for a delay period and then pulse the output. The
delay period, pulse width and pulse current are all configurable.
Mode “PU 1” will trigger from INPUT1, mode “PU 2” will trigger from
INPUT2 and mode “PU12” will trigger on either input. Triggers occur on the
leading edge of the input, that is on the transition from 0V to (for example) 5V
input

Simple and Extended Set Ups
There are two ways to set up the PP600 – Simple and Extended. Simple Set Up
can be used to set up:
Continuous output in milliamps
Pulsed output up to 99ms
