GPIO Extension (PLC IO)
The carrierboard features industrial-grade GPIOs, with 24VDC max. support in-
put/output voltage. The maximum output level depends on the output driver
voltage, which is either sourced internall (12VDC rail) or supplied externally
(24VDC max.). For the latter case, a hardware modification is necessary (Remove
R273) in order to covert the output stage to external voltage supply.
The I/Os are controlled by a MAX7325ATG I²C GPIO Expander, which also
provides the necessairy level shifting. The output driver of the expander can be
separately enabled and disabled. Additionally a fault pin exists, signaling a chip
thermal shutdown or an overcurrent condition on one or more channel(s).
