(1) 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 1770-4.1.
(2) Sourcing Output. Source describes the current flow between the I/O module and the field device. Sourcing output circuits
source current to sinking field devices. Field devices connected to the negative side (DC Common) of the field power supply
are sinking field devices. Europe: dc sinking input and sourcing output module circuits are the commonly used options.
