*1. Use shielded twisted pair cables for temperature sensors, and keep them away from power cables
and other cables that generate noise.
*2. If using 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 a Ni100 temperature sensor, a
Pt100 sensor, a JPt100, a Cu50/Cu100, or a 0~300 Ω resistance sensor, the internal excitation
current is 1.5 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.
Note: When using a three-wire temperature sensor, the cables should be the same length (less than 200
meter) and with a resistor less than 20 ohm.

*1. Use shielded twisted pair cables for temperature sensors and keep them away from power cables and
other cables that generate noise.
*2. Terminal "I12-" indicates " I1- & I2-", terminal "I34-" indicates " I3- & I4-", and terminal "I56-" indicates
" I5- & I6-". If you use two-wire temperature sensors, Ln- and In- must be short-circuited (where n is
between 1–6).
*3. There are two different internal excitation currents. If you are using a Ni100 temperature sensor, a
Pt100 sensor, a JPt100, a 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.
Note: When using a three-wire temperature sensor, the cables should be the same length (less than 200
meter) and with a resistor less than 20 ohm.
