System Overview
These Analog I/O Units belong to the CJ-series Special I/O Unit group.
• They can be mounted to CJ-series CPU Racks or Expansion I/O Racks.
The number of Units that can be mounted to one Rack (either a CPU Rack or Expansion I/O Rack) depends upon the maximum current supplied
by the Power Supply Unit and the current consumption by the other Units.
There are no restrictions on Rack position.

The sensor type, input range, and scaling can be set individually for each of 2 inputs, which are each
selectable from B, E, J, K, L, N, R, S, T, U, WRe5-26, PL II, and mV.
Temperature sensor type
Scaling
Data to be stored in the allocated words in the CIO area must be scaled (with the minimum and maximum
values set by user) (2 inputs set separately). For example, data can be stored at 0% to 100%.
The value derived from carrying out the following processing in order of the actual process data in the
input range is stored in four digits hexadecimal (binary values) in the allocated words in the CIO Area.
1) Mean value processing → 2) Scaling → 3) Zero/span adjustment → 4) Output limits

* The method for calculating the error in temperature measurements, including the temperature coefficient, is given below. The "full scale of
electromotive force" is the difference between the high limit and low limit converted to electromotive force for each thermocouple.
Example
Ambient temperature:
Temperature Sensor:
Measured temperature:
30 °C
K thermocouple (−270 to 1,372 °C)
500 °C
From electromotive force table
−270 °C:
1,372 °C:
−6.458 mV
54.86 mV
Full scale: 61.344
Electromotive conversion of temperature coefficient:
61.344 mV × 0.01%/°C = 6.13 μV/°C
Error in electromotive force at 30°C:
6.13 μV/°C x (30°C − 25°C) = 30.65 μV/°C
Temperature difference between measurement point and terminals on Unit (ambient temperature)
(based on ambient temperature of 30 °C and Measured temperature of 500 °C):
470 °C
Electromotive force per °C at a measured temperature of 470 °C (from the electromotive force
tables for a K thermocouple):
43 μV/°C
Error in temperature coefficient: 30.65 μV ÷ 43 μV/°C = 0.7°C
Error in measured temperature = Accuracy Error from temperature coefficient + Error in cold
junction compensation = 0.8°C + 0.7°C + 1.0°C = 2.5°C

Sensor Type and Input Range
The Temperature Sensor type and input range are set in the allocated words in the DM Area for every four inputs. The input range can be set
anywhere within the measurable input ranges shown in the following table. Accuracy and resolution, however, are not determined from the set
input range, but rather from the measurable input range shown in the following table. Therefore, accuracy and resolution do not change even when
a narrow input range is set.

Note: Action for Unused Input Terminals
• Short-circuit the positive (+) and negative (−) sides of the thermocouple input section using a lead wire. For example, short terminals A4
and B5 for No. 2 thermocouple input.
• Cold junction sensors are mounted between A1 and A2, and A6 and A7 before shipment. If one of the cold junction sensors is
disconnected, cold junction compensation will stop and correct measurement of temperatures cannot be made. Always make sure the
cold junction sensors are connected when using the Units.
• Cold junction sensors are calibrated separately for each Unit and connected circuit, so correct temperatures will not be measured if a cold
junction sensor from another Unit is used or if the two cold junction sensors in a Unit are swapped. Use the cold junction sensors as they
are provided, without making any changes.
• Always ground the GR terminal on the Power Supply Unit of the Controller.
• If the input device uses a voltage generator, temperature compensator, or similar device, then ground the input device if it has a ground
terminal.

Note: Action for Unused Input Terminals
• Short-circuit the positive (+) and negative (−) sides of the thermocouple input section using a lead wire. For example, short terminals A3
and A2 for No. 1 thermocouple input.
• Cold junction sensors are mounted before shipment. If one of the cold junction sensors is disconnected, cold junction compensation will
stop and correct measurement of temperatures cannot be made. Always make sure the cold junction sensors are connected when using
the Units.
• Cold junction sensors are calibrated separately for each Unit and connected circuit, so correct temperatures will not be measured if a cold
junction sensor from another Unit is used or if the two cold junction sensors in a Unit are swapped. Use the cold junction sensors as they
are provided, without making any changes.
• Do not connect anything to NC terminals. Do not use NC terminals as relay terminals.
• Always ground the GR terminal on the Power Supply Unit of the Controller.
• If the input device uses a voltage generator, temperature compensator, or similar device, then ground the input device if it has a ground
terminal.

short terminals B and b with a lead wire. If resistance is not connected between terminals A and B and terminals B and b are shorted or
if terminals A and B and terminals B and b are left open, the alarm output will turn ON and the ALM indicator will light.
3. Always ground the GR terminal on the Power Supply Unit of the Controller.
4. If the input device uses a voltage generator, temperature compensator, or similar device, then ground the input device if it has a ground
terminal.

Drop-out: Output approx. 7% max. linear (output = input) characteristic
Note: 1. The square root function can only be used when the maximum scaling value is greater than the
minimum scaling value. The square root will not be found if the maximum is smaller than the
minimum.
Function
2. When the square root function is used, set the scaling values after square root calculation (e.g.,
for flow rates or other values) for the process value scaling A and B settings.
When zero/span adjustment is executed, the date is internally recorded at the Unit. When the preset zero/
span adjustment period and the notice of days remaining set in the Expansion Setting Area have elapsed,
this function turns ON a warning flag to give notice that it is time for readjustment.
Adjustment period
control
Detects the maximum (peak) and minimum (bottom) analog input values, from when the Hold Start Bit
(output) allocated to the Expansion Control/Monitor Area turns ON until it turns OFF. These values are
stored as the peak and bottom values in the Expansion Control/Monitor Area.
Peak and bottom
detection
This function detects the top and valley values for analog inputs, from when the Hold Start Bit (output)
allocated to the Expansion Control/Monitor Area turns ON until it turns OFF. These values are stored as
the top and valley values in the Expansion Control/Monitor Area.
Top and valley

This function calculates the analog input value’s time integral. The integral value is calculated and output
to the Expansion Control/Monitor Area when the Integral Value Calculation Start Bit in the Expansion
Control/Monitor Area is turned ON.

Accuracy and Resolution in 10-V User-set Range
The 10-V user-set range allows the input signal's input range to be set to any range within −10.000 V to 10.000 V. Accuracy and resolution,
however, are not determined by the input range, but rather by the measurable input range (−10.000 V to 10.000 V). Therefore, accuracy and
resolution do not change even if a narrow input range is set.

Note: 1. Be sure to wire the correct terminals when wiring voltage inputs. The Unit may fail if a voltage input is wired incorrectly.
2. Do not connect anything to terminals that are not being used.
3. Do not connect anything to NC terminals. Do not use NC terminals as relay terminals.
4. Wire the same lengths to A, B, and b so that the impedance will be the same. In particular, do not short circuit between B and b at the
terminal block.
5. Always ground the GR terminal on the Power Supply Unit of the Controller.
6. If the input device uses a voltage generator, temperature compensator, or similar device, ground the input device if it has a ground
terminal.
7. The cold junction compensators are individually calibrated for each Unit and each input circuit. If the terminal block from a different Unit
is used, temperature measurements will not be accurate. Always use the terminal block that is delivered with the Unit.

Data to be stored in the allocated words in the CIO area must be scaled (with user-set minimum and
maximum values for data and offsets). The inputs are set individually. Data can be converted at 0% to
100%.
Scaling
The values derived from carrying out the following processing in order of the actual process data in the
input range are stored in four digits hexadecimal (binary values) in the allocated words in the Special I/O
Unit Area.
1) Averaging → 2) Scaling → 3) Zero/span adjustment → 4) Square root calculation → 5) Offset
compensation → 6) Output limits

Note: 1. When wiring voltage inputs, be careful not to connect the wrong terminals. Incorrect wiring may damage the Unit.
2. Do not remove the cold junction sensors that are connected to the CJ+ and CJ− terminals. If they are removed, compensation will not
be executed and temperatures will not be correctly measured.
3. Use the cold junction sensors that are included with the product. Cold junction sensors are calibrated for particular Units and connection
circuits. If a sensor from another Unit is used, temperatures cannot be correctly measured.
4. Use shielded cable when the resolution selection is set to 2 (1/16,000).
5. Use the same wiring length for connecting to A, B, a, and b, so that the impedance will be the same. In particular (for resistance
thermometers), do not connect the A-a and B-b terminals.
6. Do not connect anything to unused terminals.
7. Be sure to ground the GR terminal at the Power Supply Unit for the Controller.
8. Be sure to ground all input devices (such as voltage generators, temperature calibrators, and resistors) that have ground terminals.
9. Do not mount an Isolated-type Universal Input Unit on the same CPU Rack or the same Expansion Rack as a CJ1W-OC@@@ Contact
Output Unit. The Universal Input Unit measures process values at high resolution, and the noise that is generated from relay output
switching can adversely affect these operations.
10.If the CPU Rack and an Expansion Rack are lined up horizontally on the control panel and a Relay Output Unit is mounted in the same
Rack as the CJ1W-PH41U, keep the Racks separated by at least 70 mm.
11.If for some reason it is not possible to avoid mounting them on the same Rack, then mount them as far apart as possible and take
measures such as installing a surge suppressor in the relay output circuit wiring.
