Is there any relay which can be programmed to work under certain voltage, current or load range? For example, voltage range from 0V to 10V, the relay deactivates while voltage range from 10.1V to 12V, the relay activates. This applies the same for current and load range with different value of course. Basically, the relay will read the range and activates accordingly. Thanks.

Yes. Typically a "programmable relay" is a PLC coupled with a relay. Many will do what you have described so far.
