Surge Suppression - Connecting surge suppressors across your external inductive
load will extend the life of the relay contacts. For additional details, refer to Industrial
Automation Wiring and Grounding Guidelines, Allen-Bradley publication 1770-4.1.
Sinking/Sourcing Inputs - Sourcing/sinking describes the current flow between the
I/O module and the field device. Sourcing input circuits supply (source) current to
sinking field devices. Sinking input circuits are driven by a current sourcing field device.
Europe: DC sinking input and sourcing output module circuits are the commonly used options.
