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 Wiring
Basic wiring of input devices
(1)
to the 1769-IQ32T is shown below.
ATTENTION
– Miswiring of the module 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.

Sinking/Sourcing Inputs - Sourcing/sinking describes the current flow between the I/O module and the field device.
Sourcing I/O circuits supply (source) current to sinking field devices. Sinking I/O circuits are driven by a current sourcing
field device. 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.
