Current input characteristic
The following shows the list of the analog input ranges and the graph of each current input characteristic, at the current input.
No.
Input range setting
(1)
0 to 20 mA
(2)
4 to 20 mA
(3)
-20 to +20 mA
*1 When analog input exceeds the range of the digital output value, the digital output value is fixed to the maximum or minimum.
Input range setting
0 to 20 mA
4 to 20 mA
-20 to +20 mA
• Set values within the practical range of the analog input and digital output at each input range. If the values
are out of the range, the resolution and accuracy may not fall within the range of the performance
specifications. (Do not use values in the dotted line region in the graph of current input characteristics.)
• Do not set the voltage over 30 mA. Doing so can cause breakdown of the products.
