Is it possible to change 1A Io input to 5A?

It is not recommended to use 5A currents to 1A current input. 5A currents can damage 1A measurement transformers.
If you are sure that the Io current will not exceed the 1A input technical withstand values or the measurement range then 1A input can be used with 5A CT.
