Standard Connector (Thin Cables Only)
When thin cable is being used, a multi-drop connection can be made by
inserting each pair of wires into a single same pin terminal and crimping them
together.
Note
We recommend using the following PHOENIX CONTACT terminal for this
type of multi-drop connection.
• PHOENIX CONTACT AI-TWIN Series
Multi-drop Connector
The following OMRON Multi-drop Connectors (sold separately) can be used
to make a multi-drop connection with either thin or thick cable.
• XW4B-05C4-T-D Straight Multi-drop Connector without Attachment
Screws
• XW4B-05C4-TF-D Straight Multi-drop Connector with Attachment Screws
• XW4G-05C4-TF-D Straight Multi-drop Clamp Connector with Attachment
Screws
In some cases, the Multi-drop Connector cannot be used because there is not
enough space and other Units or connectors get in the way.
Note
1.
Before connecting the communications cables, turn OFF the power supply
to all PCs, Slaves, and communications power supplies.
2.
Use crimp terminals for wiring. Connecting bare twisted wires can cause
the cables to come OFF, break, or short circuit, most likely resulting in in-
correct operation and possibly damage to the Units.
3.
Use suitable crimp tools and crimping methods when attaching crimp ter-
minals. Consult the manufacturer of the tools and terminals you are using.
Inappropriate tools or methods can result in broken wires.
