How to Use the Output Interfaces

IF1 Fixed RFID Reader User Manual
Each reader output interface is optically isolated from the reader,
polarized, and rated for 5 to 30 VDC at 0.4 A.

Because the outputs are optically isolated, each one can be configured
to switch the high side or the low side of the load. You can power the load
directly from the reader or from an external power supply.
In a typical application, the outputs control indicator lamps that signal
good reads or errors. The basic methods for connecting external devices
to the GPIO outputs include:
switching the high side, with the load powered by the reader.
switching the low side, with the load powered by the reader.
switching the high side, with the load powered externally.
driving a DC relay that controls an AC load.
These methods are shown in the next examples.
