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 publication

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.
