How to Use the Power Interface
The reader GPIO interface provides 5 VDC at 0.30 A for powering
external inputs and loads, eliminating the need for an external DC supply
and simplifying the system installation.
The GPIO interface power has an internal thermal fuse that trips if the
load exceeds 0.5 A. The fuse is self-recovering after the excessive load
is removed.
The total load on the GPIO interface power must stay within the 0.5 A
limit. When you design a system that uses the GPIO interface power,
make sure to complete a power budget assessment to ensure that the
supply is adequate for the system.
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 pins. The external
supply powers the external loads, and that power is available at all +12 V
pins on the GPIO port.
