Recommended Surge Suppression - Use a 1N4004 diode reverse-wired across the load for transistor outputs switching 24V
DC inductive loads. For additional details, refer to Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley

Sourcing Output - Source describes the current flow between the I/O and the field device. Sourcing output circuits supply
(source) current to sinking field devices. 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.
