2.7. DIN Connector (Digital Inputs)
Input bits are arranged in groups of 4 and each group shares a common pin. This lets a group be
connected to current sourcing or current sinking devices, based on the connection of the common pin in
that group.
To be able to connect an input group to current sourcing devices, connect the input group's
common pin to the power supply return (-). Refer to
To be able to connect an input group to current sinking devices, connect the input group's common
pin to the power supply source (+). Refer to
.
The digital inputs are not designed for high-voltage isolation applications. They should only be used with
ground-referenced circuits.
