Grounding the Module
This product is intended to be mounted to a well-grounded mounting surface such as a metal
panel. Additional grounding connections from the module’s mounting tabs or DIN rail (if
used), are not required unless the mounting surface cannot be grounded. Refer to Industrial
Automation Wiring and Grounding Guidelines, Allen-Bradley publication 1770-4.1, for additional
information.
Output Wiring
Basic wiring (1) of output devices (2) to the 1769-OV32T is shown below.
ATTENTION
• Miswiring of the module to an AC power sink or applying reverse
polarity will damage the module.
• Be careful when stripping wires. Wire fragments that fall into a
module could cause damage at power up. Once wiring is complete,
ensure the module is free of all metal fragments.
(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) Sinking Output - sink describes the current flow between the I/O module and the field device. Sinking output circuits sink
current from sourcing 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.
