Is it possible to put multiple channels of a digipot in serie?

I have a ad5206 digipot. And i was wondering if it is possible to put all the 6 channels in serie. So if 1 channel can be max 100Kohm. Putting all 6 channels in serie would be 600Kohm?

I want to replace a 500Kohm manual potmeter with a digital one. The potmeter is being used to provide input for a variable solid state relais.

http://www.kyotto.com/eng_KR20.htm here u can find the technical details for the ssr.

I have no clue if its possible to use a potmeter in this case nor how to wire it.

Can you give me some hints,tips please

You don't want a pot, it has to be a variable resistor.

The voltage appears too great for the AD5206.

Better to design a better level detector and relay driver yourself.
