• Manufacturer Part Number: CJ1W-AD042
• Description: ANALOG IN, CJ1, 4CH, HIGH SPPE
• Manufacturer: Omron

Specifications of CJ1W-AD042

• Lead Free Status / Rohs Status: Lead free / RoHS Compliant

Output Specifications
*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
*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
*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
*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
*7 By means of the D (m+18) setting, the resolution can be changed to 8,000, and the conversion period can be changed to 500 μs.

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.
ON, the Output Conversion Enable Bit will turn OFF. The output status specified according to the output hold function will be output.

Outputs the specified output status (CLR, HOLD, or MAX) under any of the following circumstances.
Enabled only for conversion period or 1 ms and resolution of 4,000. Setting any values within a range of
±32,000 as the upper and lower limits allows D/A conversion to be executed and analog signals to be output
with these values as full scale.
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
Negative gradient:Analog output = F − A × Analog input + B
Supported
• When the Conversion Enable Bit is OFF. *6
• In adjustment mode, when a value other than the output number is output during adjustment.
• When output setting value error occurs or PLC operation stops.
• When the Load is OFF.
