External Wiring Example

The followings show the examples of external wiring.
Voltage input, and current input
24 V DC
Grounding
(Grounding resistance: 100  or less)
CH
Shielded wire
For  in CH, the CH number is entered.
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.
24 V DC
Grounding
(Grounding resistance: 100  or less)
Compensating conductor
(shielded wire)
For  in CH, the CH number is entered.
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.
24 V DC
Grounding
(Grounding resistance: 100  or less)
Shielded wire
For  in CH, the CH number is entered.
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.
