*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.

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.
