FX5U CPU module has 2 built-in voltage input channels (DC0~10V) and 1 built-in voltage output channel (DC0~10V).
If an external resister is connected, the module can also support current input (DC4~20mA).
For further details, please refer to MELSEC iQ-F FX5 User's Manual (Analog Control - CPU module built-in, Expansion adapter).
Because the FX5UC CPU modules do not have a built-in analog function, please use an analog adapter or intelligent function module.
