7 8-Input-Output Board
This chapter describes one of the interface boards employed by the AEC2.1. This section
identifies and locates key components on the board and includes a brief overview of the
functional operation.
The 8-IO board provides eight zones of end-of-line resistor type inputs and eight contact
closure outputs. This board is intended for non-reader type applications where it is desirable
to monitor emergency exit doors, or motion detectors. This board also provides eight Form-C
type relay outputs, which can be used to control external equipment, such as lights, gate
motor, etc.
The board size and location of mounting holes on both the 4-Reader board and 8-IO board are
the same.
