	Limiting Simultaneous Outputs	This function limits the number of outputs that turn ON simultaneously by shifting the control period of each output and restricting the upper limit of the manipulated variable. You can set a delay between outputs, which allows delays in output device operation that can occur when outputs are switched.	Standard control type models with voltage output (for driving SSR)
Error Detection	Sensor Disconnection Detection	This function detects disconnections in temperature sensors. It also detects that the measured value of the temperature sensor is outside the input indication range.	All models

      For thermocouple inputs, reference accuracy and cold junction compensation error are guaranteed for a set of a
      Temperature Control Unit and a terminal block on which a cold junction sensor is mounted.
      Be sure to use the terminal block and the Temperature Control Unit with the same calibration control number
      together.
      A calibration control number is displayed both on the terminal block and the Unit.
      In order to distinguish left and right terminal blocks, each terminal block has either a letter "L" (left side) or "R" (right
      side) appended at the end of a calibration control number.
      Make sure to return the terminal block to which a cold junction sensor is mounted and the Unit together.

*1. The decimal point position of the various input types is "no decimal point" or "decimal point 1 digit". When calculating
      measured value error, round up calculation results in accordance with the decimal point position of the temperature
      range.
*2. The overall accuracy of the Temperature Control Unit is guaranteed for a set consisting of a cold junction sensor that
      is mounted on the terminal block and a Temperature Control Unit. Be sure to use the terminal block and Temperature
      Control Unit with the same calibration control number together. For the 24mm width model, also be sure the left and
      right terminal blocks are correctly attached.

*3. An error for a measured value when the ambient temperature changes by 1°C.
     The following formula is used to calculate the error of the measured value for thermocouple inputs..
     Overall accuracy = Reference accuracy + Temperature characteristic x Change in the ambient temperature + Cold
     junction compensation error For resistance thermometer inputs, there is no cold junction compensation error.
     (Calculation example)

Item	Description
Ambient temperature	30°C
Measured value	100°C
Thermocouple	K: -200 to 1300°C

Item	Description
Reference accuracy	-100 to 400°C: ±1.5°C
Temperature coefficient	-100 to 400°C: ±0.30°C/°C
Change in the ambient temperature	25°C -> 30°C 5 deg
Cold junction compensation error	±1.2°C

Therefore,
Overall accuracy = Reference accuracy + Temperature characteristic x Change in the ambient temperature +
Cold junction compensation error
= ±1.5°C +(±0.30°C/°C) x 5 deg + ±1.2°C
= ±4.2°C
-200 to 1300°C without decimal point. the calculation result is round up after the decimal point.
Then the overall accuracy is ±5°C.

*4. The ppm value is for the full scale of the temperature range.

This section describes the cold junction compensation errors for thermocouple inputs, which differ by installation orientation of this Unit, type of adjacent Units, and current consumed by the adjacent Units.

This section describes the cold junction compensation errors when the adjacent Units are Temperature Control Units. The error differs by installation orientation.

The cold junction compensation error is ±1.2°C.
However, there are exceptions depending on the input type and temperature. Those conditions and the cold junction compensation error are as in the table below.

Input type and temperature range	Cold junction compensation error
T below -90°C	±3.0°C
J, E, K and N below -100°C
U, L and PLII
R and S below 200°C
B below 400°C	Not guaranteed
C/W	±3.0°C

The cold junction compensation error is ±4.0°C.
However, there are exceptions depending on the input type and temperature. Those conditions and the cold junction compensation error are as in the table below.

Input type and temperature range	Cold junction compensation error
T below -90°C	±7.0°C
J, E, K and N below -100°C
U, L and PLII
R and S below 200°C
B below 400°C	Not guaranteed
C/W	±9.0°C

This section describes the cold junction compensation errors when the adjacent Units are not Temperature Control Units. The error differs by the installation orientation and power consumption by the adjacent Units.

The cold junction compensation error is ±1.2°C.
However, there are exceptions depending on the input type and temperature. Those conditions and the cold junction compensation error are as in the table below.

Input type and temperature range	Cold junction compensation error
T below -90°C	±3.0°C
J, E, K and N below -100°C
U, L and PLII
R and S below 200°C
B below 400°C	Not guaranteed
C/W	±3.0°C

(b) When the power consumption of either the left or the right adjacent Unit is more than 1.5 W but less than 3.9 W.
Or for any installation other than upright, when the power consumption of both the left and right adjacent Units is
less than 3.9 W

The cold junction compensation error is ±4.0°C.
However, there are exceptions depending on the input type and temperature. Those conditions and the cold junction compensation error are as in the table below.

Input type and temperature range	Cold junction compensation error
T below -90°C	±7.0°C
J, E, K and N below -100°C
U, L and PLII
R and S below 200°C
B below 400°C	Not guaranteed
C/W	±9.0°C

Do not use the above condition (c) because the cold junction compensation error is not guaranteed in this condition.

The power consumption of adjacent Units is the total of the following values.
• The power consumption of the NX Unit power supply and I/O power supply for the NX Units adjacent to the Temperature Input Unit. If the adjacent Unit is an Input Unit, it is the total power consumption according to the input current.

Refer to the user's manual for the CPU Unit for details on the CPU Units to which NX Units can be connected.
