Wiring the Terminals
This section describes how to wire the terminals on the Digital I/O Units.
This section describes how to connect wires to the screwless clamping terminal block, the installation
and removing methods, and functions for preventing incorrect attachment.
You can connect ferrules that are attached to the twisted wires to the screwless clamping terminal
block. You can also connect the twisted wires or the solid wires to the screwless clamping terminal
block. If you connect the ferrules, all you need to do to connect the wires is to insert the ferrules into the
terminal holes.
The terminals to be wired are as follows.
• I/O power supply terminals
• I/O terminals
Make sure that the voltages and currents that are input to the Units and slaves are within the speci-
fied ranges.
Inputting voltages or currents that are outside of the specified ranges may cause accidents or fire.
