ATTENTION: Follow these guidelines:
• Miswiring of the module to an AC power source or applying reverse
polarity will damage the module.
• Be careful when stripping wires. Wire fragments that fall into a module
could cause damage at powerup. Once wiring is complete, make sure the
module is free of all metal fragments.
(1) Recommended Surge Suppression - The module has built-in suppression which is sufficient for most applications, however, for
high-noise applications, use a 1N4004 diode reverse-wired across the load for transistor outputs switching 24V DC inductive
loads. For additional details, refer to the Industrial Automation Wiring and Grounding Guidelines, publication
1770-4.1.
(2) Sourcing Output - Source describes the current flow between the I/O module 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 module circuits are the commonly used options.
