)
1. 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. Europe: DC sinking input and sourcing output module circuits are the commonly
used options.
