Individual Specifications
Analog Input Units CJ1W-AD041-V1/AD081-V1/AD042
Specifications
*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
*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
*6 The resolution can be set to 8,000 and the conversion period to 250 μs in the DM Area (m+18). There is only one setting for both of these, i.e.,
*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.
*8 For the CJ1W-AD041-V1/ AD081-V1, 23±2
*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
*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

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.
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.)

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, 64, 128, 256, 512
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.
A/D conversion is performed and the
converted value is refreshed when the
ANALOG INPUT DIRECT CONVER-
SION instruction (AIDC) is executed.
This instruction is supported by the
CJ2H-CPU@@(-EIP) CPU Units with
unit version 1.1 or later.
CJ1 and CP1H CPU Units and NSJ
Controllers do not support direct con-
version.
