22 GPIO Terminal Block User’s Guide
If your system needs more than +12 VDC at 0.5 A, you can connect an
external power supply to the +12 V and Ground posts on the power
terminal. The external supply will power the external loads, and that
power will be available at all +12 V posts on the input and output
terminals.
Sample System Diagram
This illustration shows how to connect a system that uses position
detection sensors as inputs and indicator lamps as outputs. All are
connected to the power terminal on the terminal block and powered
by the reader.
