Features
Analog Input Units
• Input up to eight analog signals with one Unit.
• Functions include line disconnection detection, averaging, peak value holding, offset/gain adjustment, and scaling.
(Offset/gain adjustment is not supported by the CJ1W-AD042. Scaling is supported only by the CJ1W-AD042.)
• High-speed A/D conversion in 20 μs/point with direct conversion function * (CJ1W-AD042 only).
Analog Output Units
• Output up to eight analog signals with one Unit.
• Functions include output holding, offset/gain adjustment, and scaling. (Offset/gain adjustment is not supported by the CJ1W-DA042V. Scaling
is supported only by the CJ1W-DA08V/DA08C/DA042V.)
• High-speed D/A conversion in 20 μs/point with direct conversion function * (CJ1W-DA042V only).
Analog I/O Units
• Input up to four analog signals and output up to two analog signals with one Unit.
• Functions include line disconnection detection, input averaging, scaling, input peak value holding, output holding, ratio conversion, and offset/
gain adjustment.
* Direct Conversion Instructions for High-speed type can be used to create a consistent response time from input through data processing and
output. With the Machine Automation Controller NJ-series, the direct conversion function cannot be used. This function is supported only by the
CJ-series CPU Unit.

A/D conversion is performed and the

the ANALOG INPUT DIRECT CONVERSION instruction (AIDC) is executed. This instruction is supported
by the CJ2H-CPU@@ (-EIP) CPU
Units with unit version 1.1 or later,
and CJ2M-CPU@@.
CJ1, NJ501, and CP1H CPU Units
and NSJ Controllers do not support
direct conversion.
*1 Do not apply a voltage higher than 600 V to the terminal block when performing withstand voltage test on this Unit. Otherwise, internal elements
may deteriorate.
*2 Input signal ranges can be set for each input.
*3 Voltage input or current input are chosen by using the voltage/current switch at the back of the terminal block.
*4 To use a current input, connect the positive current input terminal and positive voltage input terminal with the enclosed short bar.
*5 The Analog Input Unit must be operated according to the input specifications provided here. Operating the Unit outside these specifications
will cause the Unit to malfunction.
*6 The resolution can be set to 8,000 and the conversion period to 250 μs in the setting. There is only one setting for both of these, i.e., they are
both enabled or disabled together.
*7 The accuracy is given for full scale. For example, an accuracy of ±0.2% means a maximum error of ±8 (BCD) at a resolution of 4,000.
For the CJ1W-AD041-V1/ AD081-V1, the default setting is adjusted for voltage input. To use current input, perform the offset and gain
adjustments as required.
*8 For the CJ1W-AD041-V1/ AD081-V1, 23±2°C.
*9 The A/D conversion period is the time required from when the Analog Input Unit receives the analog signal until it stores the converted value
in internal memory. It takes at least one cycle for the converted data to be stored in the CPU Unit. (The direct conversion function of the CJ1WAD042 is can be used to input data immediately to the CPU Unit.)
*10 Line disconnection detection is supported only when the range is set to 1 to 5 V or 4 to 20 mA. If there is no input signal when the 1 to 5 V or
4 to 20 mA range is set, the Line Disconnection Flag will turn ON.

with these values as full scale.
Ratio conversion function *5
Stores the results of positive and negative gradient analog inputs calculated for ratio and bias as analog output
values.
Positive gradient: Analog output = A × Analog input + B
(A: 0 to 99.99, B: 8000 to 7FFF hex)
Negative gradient:Analog output = F − A × Analog input + B
(A: 0 to 99.99, B: 8000 to 7FFF hex, F: Output range maximum value)
Offset/gain adjustment
Supported
*1 Input and output signal ranges can be set for each input and output.
*2 Voltage input or current input are chosen by using the voltage/current switch at the back of the terminal block.
*3 The Analog I/O Unit must be operated according to the input specifications provided here. Operating the Unit outside these specifications will
cause the Unit to malfunction.
*4 The accuracy is given for full scale. For example, for an input, an accuracy of ±0.2% means a maximum error of ±8 (BCD) at a resolution of
4,000. For an output, an accuracy of ±0.3% means a maximum error of ±60 mV for a −10 to 10 V range.
*5 The A/D conversion period is the time required from when the Analog Input Unit receives the analog signal until it stores the converted value
in internal memory. It takes at least one cycle for the converted data to be stored in the CPU Unit.
The D/A conversion period is the time required for the Analog Output Unit to convert and output the data that was received from the CPU Unit.
It takes at least one cycle for the data stored in the CPU Unit to be read by the Analog Output Unit.
*6 When the operation mode for the CPU Unit is changed from RUN mode or MONITOR mode to PROGRAM mode, or when the power is turned
ON, the Output Conversion Enable Bit will turn OFF. The output status specified according to the output hold function will be output.
*7 By means of the setting, the resolution can be changed to 8,000, and the conversion period can be changed to 500 μs.

2. The AG terminals are connected to the 0 V analog circuit in the Unit. Connecting shielded input lines can improve noise resistance.
3. Do not connect anything to NC terminals.
4. To use a current input with the CJ1W-AD042, connect the positive current input terminal and positive voltage input terminal with the
enclosed short bar.

2. The N.C. terminals are not connected to internal circuit.
3. Use a separate power supply from the one used for Basic I/O Units. Faulty Unit operation may be caused by noise if power is supplied
from the same source. (This does not apply to CJ1W-DA042V.)
