Sinking/Sourcing Inputs - Sinking/Sourcing 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.
