External Wiring Example
The followings show the examples of external wiring.
Voltage input, and current input
Precautions
Use a two-conductor shielded twisted pair cable for analog input lines and carry out the wiring while separating them from
other power lines and lines susceptible to induction.
Thermocouple
Refer to

Page 15 Thermocouple input specifications for the thermocouples that can be used with multiple input module.
Precautions
When using thermocouple input, use the prescribed compensation lead wire.
Resistance temperature detector
Refer to

Page 16 Resistance temperature detector (RTD) input specifications for the resistance temperature detector that
can be used with multiple input module.
Precautions
When using the resistance temperature detector, carry out the wiring with a wire with low lead wire resistance and no
resistance difference between the lead wires.
