Wire the DC-Input/Relay-Output Combination Module
Basic wiring of inputs
(1)
and outputs
(2)
is shown below.
A write-on label is provided with the module. Mark the identification of each terminal with
permanent ink, and slide the label back into the door.
(1) Sinking/Sourcing Inputs - Sinking/Sourcing 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.
(2) 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.
ATTENTION
Be careful when stripping wires. Wire fragments that fall into a module
could cause damage when power is applied. Once wiring is complete, ensure
the module is free of all metal fragments.
