Can I daisy chain the Switching Relay - 4 or 8 using RS-232 loop through?

Yes, you can daisy chain up to eight Switching Relay – 4 or 8 units, providing you with up to 64 relay options.

However, you do need to set a different UNIT ID for each 4/8-Relay box.

Use this code:

NEUNIT=1,UNITID=X<CR>

Change X to the UNIT ID you need and remember to save the change with: 

NEUNIT=1,SAVE=TRUE<CR>
