*1. Do not apply a voltage higher than 600 V to the terminal block when performing withstand voltage test on this Unit.
*2. Refer to Dimensions for details on the Unit's dimensions.
*3. Maximum Number of Units

3 Units max. 2 Units max.
C200HW-PA209R 7 Units max. 5 Units max.

        The maximum number of Units that can be mounted to one Rack varies depending on the current consumption of
        the other Units mounted to the Rack and may be less than the number shown in the above table.
*4. Data Exchange with CPU Units

*5. Output signal ranges can be set for each output.
*6. The accuracy is given for full scale. For example, an accuracy of ±0.3% means a maximum error of ±12 (BCD).
*7. 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.
*8. 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.
*9. The load resistance is adjusted to 250 Ω at the factory. Always adjust the offset gain before application when the load
       resistance is not 250 Ω.
       The CS1W-DA041 is adjusted for current outputs (load resistance: 250 Ω) at the factory. Adjust the offset gain before
       application when using voltage outputs.
