• Manufacturer Part Number: cs1w-ad
• Description: Cs Series Analog I/o Unit
• Manufacturer: Omron Corporation

*4. Data Exchange with the CPU Unit
*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
*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
*9. The following are adjusted at the factory.
*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
*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
