External Wiring Example

An external wiring example is shown below.
Thermocouple
For thermocouples usable with the temperature control module, refer toPage 17 Input specifications.
24 V DC
Grounding
(Ground resistance: 100  or less)
Compensating
Thermocouple
lead wire
Shielded wire
CH: represents the channel number.
Precautions
When using a thermocouple, use specified compensating lead wires.
Resistance thermometer
For resistance thermometer usable with the temperature control module, refer toPage 17 Input specifications.
Pt100 (3-wire type) or Pt1000 (3-wire type)
24 V DC
Grounding
(Ground resistance: 100  or less)
Pt100 or Pt1000
Shielded wire
CH: represents the channel number.
Precautions
• When using a resistance thermometer, use lead wires of equal, low resistance.
• Make sure to short-circuit the [B] and [b] terminals when a 2-wire resistance thermometer is input.
