ATTENTION
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.
