Installation & Service Manual
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.
• For GPI outputs, terminals identified as N and P are used only.
• For GPI inputs, terminals identified as GND and P are used only.
CAUTION
In the example below, make sure your P and N connections are in the
proper polarity otherwise the GPI output will always be ON.
