RS-422 Communications Wiring
The RS-422 Connector pin arrangement is as follows:
• Multidrop wiring can be used. (The left and right terminals are internally
connected to allow multidrop connections).
• Connect the RS-422 in a 1:1 or a 1: N configuration.
For a 1:N configuration, up to 32 nodes can be connecting, including the
host computer or PLC.
• The total cable length is 500 m max.
• Use shielded, twisted-pair cables with a wire gauge of AWG24 to AWG12.
Note
1.
The following crimp terminals are recommended for cables.
• Phoenix Contact AI Series
AI0, 5-8 (AWG20) or other (Use a crimp terminal appropriate for the
wire diameter)
The following tool is recommended.
ZA3 manufactured by Phoenix Contact
• Nichifu TC Series
TME TC-1.25-11 (AWG22 to AWG16) or other (Use a crimp terminal
appropriate for the wire diameter.)
The following tool is recommended.
