2. Performance Specifications
The following table shows the performance specifications of the A1S68AD.
*1: The switch is set to an analog input value of 0 to +10V on delivery.
*2: The maximum conversion speed is 1ms/channel on all channels if
averaging processing is set even for only one channel.
*3: For the selecting method of voltage input or current input, refer to
Chapter 3.
*4: Current value indicates value of instant input current that does not
break module inner electrical resistance.
