Auxiliary Input/Output (I/O) Board
The Auxiliary I/O Board (A4) is an optional component that mounts near the top of the heat sink
on the left side of the ATevo . It is equipped with six (6) relays, four (4) generic Binary Inputs,
and four (4) generic Analog Inputs.
The Auxiliary I/O Board (A4) communicates to the Main Control Board (A1) via serial
communications. The Serial Communications Connection is part of the ribbon cable between
the Main Control Board and the Power Board (A2). A green communications LED is located
adjacent to the TB2 terminal block of the Auxiliary I/O Board.
This LED will blink to indicate active communication between the Auxiliary I/O Board and the
Main Control Board. All relays are failsafe such that if communication is lost between the Main
Control Board (A1) and the Auxiliary I/O Board (A4), the relays will switch to the alarm state.
