 ===== Example =====
+Connect an X input module to MPAINO-8A8R(T) and select **Analog Input Module → X**. Set CH0 DIP switches 20mA and GND to ON, then connect the 4–20mA signal.

 ===== Precautions =====
-  * Set the module DIP switches and wiring for 0~20mA current I/O.
+  * Set the MPAINO X module CH0 DIP switches 20mA and GND to ON, and wire the current input with the correct polarity.
   * An input of approximately 3.6~4.0mA returns the normal value ''0''; inputs below 3.6mA return an error value.
   * Error values help detect open circuits. The user must implement final alarms and safety actions in the program.
