reTerminal DM / Input ,Output Level

What is the DI/DO input threshold high level and output high level of the reTerminal DM?

In the data sheet the typical voltage range is 5V to 24V, but this is too wide.

Hi, Please note that the DI/DO are designed with industrial compliant which is differ from the GPIO on the 40pin GPIO header of raspberry pi, The DI/DOs are opto isolated which can handle a bit wide range of the voltage commonly used in the industrial standard environment, therefore the hardware wiring is also a bit different. Please refer to the wiki page of the wiring schematic drawing for reference:

Thank you for answering.
i understood.
