(1) Sinking Input - Sink describes the current flow between the I/O module and the field device. Sinking I/O circuits are
driven by a current sourcing field device. Field devices connected to the positive side (+V) of the field supply are
sourcing field devices. Europe: DC sinking input and sourcing output module circuits are the commonly used options.
