(1) Sinking/Sourcing Inputs - Sourcing/sinking describes the current flow between the I/O 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. Europe: DC sinking input and sourcing output circuits are the commonly used options.
