Sinking/Sourcing Inputs - Sourcing/sinking describes the current flow between the I/O module and the
field device. Sourcing I/O circuits supply (source) current to sinking field devices. Sinking I/O circuits are
driven by a current sourcing field device. Field devices connected to the negative side (DC Common) of
the field power supply are sinking field devices. Field devices connected to the positive side (+V) of the
field supply are sourcing field devices.
