Wiring CJ-series Basic I/O Units with Terminal Blocks

Precautions for Wiring I/O Units
I/O Unit Specifications
Double-check the specifications for the I/O Units. In particular, do not apply a voltage that exceeds
the input voltage for Input Units or the maximum switching capacity for Output Units. Doing so may
result in breakdown, damage, or fire.
When the power supply has positive and negative terminals, be sure to wire them correctly.

Electric Wires

• The following wire gauges are recommended.
Terminal Block Connector
18-terminal
• The current capacity of electric wire depends on factors such as the ambient temperature and
insulation thickness as well as the gauge of the conductor.
Crimp Terminals
The terminals on the I/O Unit are M3, self-raising terminals with screws.
Precautions for Correct Use
Precautions for Correct Use
• Use crimp terminals for wiring.
• Do not connect bare stranded wires directly to terminals.
