4.10 Wiring Temperature Measurement Modules

Ni100/Ni120/Ni1000/Pt100/Pt1000

Cu50/Cu100/JPt100/LG-Ni1000

*1. Use shielded twisted pair cables for temperature sensors, and keep them away from power cables and

*2. If you use two-wire temperature sensors, Ln- and In- must be short-circuited (where n is between 1–4).

*3. There are two different internal excitation currents. If you are using temperature sensors, such as Ni100,

Note: use cables with the same length (less than 200 m) and use terminal resistors of less than 200 ohm.

other cables that generate noise.

Ni120, Pt100, JPt100, Cu50/Cu100, or a 0~300 Ω resistance sensor, the internal excitation current is

1.0 mA. If you are using a Ni1000 temperature sensor, a Pt1000 temperature sensor, a LG-Ni1000

sensor, or a 0~3000 Ω resistance sensor, the internal excitation current is 0.2 mA.
