Overvoltage on Analog Input: If a voltage applied to an analog input exceeds the power specification of the board, the input
multiplexer and/or parts behind it can be damaged. Most Diamond Systems boards will withstand an erroneous
connection of up to 36V on the analog inputs, even when the board is powered off, but not on all boards, and not under
all conditions.
Overvoltage on Analog Output: If an Analog output is accidentally connected to another output signal or a power supply
voltage, the output can be damaged. On most Diamond boards, a short circuit to ground on an analog output will deter
any damage to the board.
Overvoltage on Digital I/O Line: If a Digital I/O signal is connected to a voltage above the maximum specified voltage, the
digital circuitry can be damaged. The acceptable voltage range on most Diamond Systems boards connected to digital
I/O signals is 0-5V, with overvoltage protection up to 5.5V (-0.5 to 5.5V). Overvoltage beyond this limit can damage the
circuitry.
Other considerations are Logic Signals, which are typically generated between 12V to 24V.
If a Digital I/O Line of 12V to 24V is connected to a 5V logic chip, the chip will be damaged, and the damage could extend to
other chips in the circuit.
IMPORTANT! Always check twice before Powering Up!
