GPI Circuits
The individual GPI contacts are reconfigurable as either inputs or outputs. For interfacing
purposes, the input and output circuit configurations are as shown in the following
diagrams:
You should ensure your GPI physical connections are well established. In the following
example, the goal is to trigger a relay and light up a light.
To facilitate cabling of the GPI inputs and outputs, a terminal block adapter is available
separately (order code KXA-TBA-G). The GPI Terminal Block Adapter accommodates up to
24 terminal block connections using positive and negative terminal connections. Each
column on the terminal block has 6 positive and 6 negative terminal connections that
correspond to each pin position. Negative pins (labelled with an N) on the Terminal Block

CAUTION
In the example below, make sure your P and N connections are in the
proper polarity otherwise your GPI output will always be in the ON state.
