*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. Refer to Dimensions for details on the Unit's dimensions.
*3. The maximum number of Analog Input Units that can be mounted to one Rack depends on the Power Supply Unit
       mounted to the Rack.

Power Supply Unit	Rack	CS1W-AD041-V1 CS1W-AD081-V1 (5 VDC 120 mA)	CS1W-DA041 CS1W-DA08V (5 VDC 130 mA)	CS1W-MAD44 (5 VDC 200 mA)	CS1W-DA08C (5 VDC 130 mA)	CS1W-AD161 (5 VDC 150 mA)

        The above limits may be reduced depending on the power consumed by other Units on the same Rack.
*4. Data Exchange with the CPU Unit

Area	Number of words	Data transfer timing	Transfer direction	Data contents
Special I/O Unit Area in CIO Area (CIO 2000 to CIO 2959, CIO 2000.00 to CIO 2959.15)	CS1W-AD041-V1/081-V1: 10 words per Unit CS1W-AD161: 20 words per Unit	Constantly	CPU Unit to Analog Input Unit	Peak hold indicators
			Analog Input Unit to CPU Unit	Analog input values Line disconnection detection Alarm flags Etc.
Special I/O Unit Area in DM Area (D20000 to D26959)	CS1W-AD041-V1/081-V1: 100 words per Unit CS1W-AD161: 200 words per Unit	When power is turned ON or Unit is restarted	CPU Unit to Analog Input Unit	Input signal conversion ON/OFF Signal range specifications Averaging specifications Resolution/conversion time setting Operation mode setting Scaling setting (CS1W-AD161 only)

        The resolution/conversion time setting and operation mode setting are supported only by version-1 Analog Input
        Units.
*5. Input signal ranges can be set for each input.
*6. Voltage input or current input is selected for the CS1W-AD041-V1 and CS1W-AD081-V1 by using the voltage/current
       switch at the back of the terminal block. Voltage input or current input is selected for the CS1W-AD161 by wiring the
       connector terminals. Voltage/current selection for input ranges 1 to 5 V or 4 to 20 mA can be set in DM word m+52.
*7. Use the analog input voltage/current value within the specified input signal range. Exceeding the specified range may
       result in malfunction.
*8. With Analog Input Units, the resolution can be changed from 4,000 to 8,000 and the conversion time changed from 1
       ms to 250 μs in DM word m+18 for CS1W-AD041-V1 and CS1W-AD081-V1 or in DM word m+19 for CS1W-AD161.
*9. The following are adjusted at the factory.
       CS1W-AD041-V1/081-V1: Voltage inputs
       CS1W-AD161: Voltage inputs and current inputs
                                  Calibration conditions: Recommended Terminal Block-Connector Conversion Unit used. (The
                                  factory calibration for a current input can be made effective by setting DM word m+52.)
       To use current inputs with the CS1W-AD041-V1/081-V1 or to use the CS1W-AD161 with products other than the
       recommended ones, adjust the offset and gain as required.
*10. A/D conversion time is the time it takes for an analog signal to be stored in memory as converted data after it has
         been input. It takes at least one cycle before the converted data is read by the CPU Unit.
*11. Input disconnection detection is valid only when the 1 to 5-V or 4 to 20-mA range is set. If there is no input signal
         for when the 1 to 5-V or 4 to 20-mA range is set, the Disconnection Detection Flag will turn ON.
