| Output hold function | Outputs the specified output status (CLR, HOLD, or MAX) under any of the following circumstances. When the Conversion Enable Bit is OFF. *7 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 CPU Unit is on standby. When the Load is OFF. | ||||
| Scaling function | Setting values in any specified unit 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.

*1.Do not apply a voltage higher than 600 V to the terminal block when performing withstand voltage test on this Unit.
*2.The maximum number of Analog Output Units that can be mounted to one Rack varies depending on the current consumption of the other Units mounted to the Rack.
Select a 24-VDC power supply based on the surge current. The following OMRON external power supplies are recommended.
| Manufacturer | Model number | Specifications |
| OMRON | S8VS-06024 | 100 to 240 VAC, 60 W |
| S8VS-12024 | 100 to 240 VAC, 120 W | |
| S8VM-05024 | 100 to 240 VAC, 50 W | |
| S8VM-10024 | 100 to 240 VAC, 100 W |
*3.Data exchange methods with the CPU Unit are as follows:
| Special I/O Unit Area in CIO Area CIO 2000 to CIO 2959 (CIO 200000 to CIO 295915) | 10 words per Unit Refreshed cyclically | CPU Unit to Analog I/O Unit | Analog output values Conversion enable bits |
| Analog I/O Unit to CPU Unit | Alarm flags | ||
| Special I/O Unit Area in DM Area D20000 to D29599 | 100 words per Unit Refreshed at power ON or restart | CPU Unit to Analog I/O Unit | Output signal conversion settings and signal range settings Output status when holding outputs |
*4.Output signal ranges can be set for each output.
*5.The accuracy is given for full scale. For example, an accuracy of ±0.3% means a maximum error of ±12 (BCD) at a resolution of 4,000. For the CJ1W-DA021/041, the accuracy is at the factory setting for a current output. When using a voltage output, adjust the offset gain as required.
*6.D/A conversion time is the time required for converting and outputting the PLC data. It takes at least one cycle for the data stored in the PLC to be read by the Analog Output Unit.
*7.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.
*8.The CJ1W-DA08V/08C can be set to a conversion cycle of 250 μs and a resolution of 8,000 using the setting in D(m+18).
