198 Programmable Controllers
CJ1W-AD@@@(SL)
Analog Input Units
Convert Analog Signals to Binary Data
• Wire burnout detection
• Peak-hold function
• Mean function
• Offset gain setting
• Range selection per intput
• 1/8000 resolution
• 2 ms conversion time for 8 channels
Function
Convert input signals such as 1 to 5 V or 4 to 20 mA to binary values between 0000 and 1F40 Hex and store the results in the allocated words
each cycle. The ladder diagram can be used to transfer the data to the DM Area or the SCALING instructions (e.g., SCL(194)) can be used to scale
the data to the desired range.
