functionsMean value processing
Stores the last "n" data conversions in the
buffer, and stores the mean value of the
conversion values.
Buffer number: n = 2, 4, 8, 16, 32, 64Stores the last "n" data conversions in the
buffer, and stores the mean value of the
conversion values.

n = 2, 4, 8, 16, 32, 64, 128, 256, 512Peak value holding
Stores the maximum conversion value while the Peak Value Hold Bit is ON.
Scaling
---
Setting values in any specified unit within a
range of ±32,000 as the upper and lower limits
allows A/D conversion to be executed and
analog signals to be output with these values as
full scale.Input disconnection
detectionDetects the disconnection and turns ON the Disconnection Detection Flag. *10
Offset/gain adjustment
Supported
---
Direct conversion
---
A/D conversion is performed and the converted
value is refreshed when 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 CJ1W-AD042 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.
