Field Wiring Connections
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.
Input/Output Wiring
Basic wiring
(1)
of input
(2)
and output devices to the 1769-IQ6XOW4 is shown
below.
(1) Surge Suppression - Connecting surge suppressors across your external inductive load will extend the life of the relay
contacts. For additional details, refer to Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley publication
1770-4.1.
(2) Sinking/Sourcing Inputs - Sourcing/sinking describes the current flow between the I/O module and the field device.
Sourcing input circuits supply (source) current to sinking field devices. Sinking input circuits are driven by a current sourcing
field device.
Europe: DC sinking input and sourcing output module circuits are the commonly used options.
ATTENTION
!
•
Miswiring of the module’s inputs to an AC power source
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.
