General Purpose Inputs / Outputs
The functional scope of the carrierboard has been extended by GPIOs which
support a maximum of 24V at the input. The maximum output level depends on the
input voltage which is limited to 24V. For lower input voltages an external voltage
up to 24V can alternatively be supplied. In that case a hardware modification is
necessary.
Inputs and outputs are controlled by a MAX7325ATG I²C GPIO Expander. The
output pins are level shifted to either the input voltage or to the level of an
externally supplied voltage. The output driver can be separately enabled and
disabled. Additionally a fault pin exists that signals a chip thermal shutdown or an
overcurrent condition on any channel.
