+Connect a Y output module to MPAINO-8A8R(T) and select **Analog Output Module → Y**. Set the CH0 DIP switch to OFF and measure the 4–20mA output at ''I+'' and ''−''.

 ===== Precautions =====
-  * Set the module DIP switches and wiring for 0~20mA current I/O.
+  * Set the MPAINO Y module CH0 DIP switch to OFF and connect the 4–20mA output to ''I+'' and ''−''.
   * 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.

   * The analog output circuit requires an external 12~24V supply. USB power alone may not provide normal output.
   * Verify actual current input/output with measuring instruments after preparing a test product.
