Re: What do people use for terminal blocks in Node 0?

Hi Paul,

In industrial control panels you'd typically use something like these:
https://www.phoenixcontact.com/online/portal/gb?1dmy&urile=wcm%3apath%3a/gben/web/main/products/subcategory_pages/Installation_terminal_blocks_P-15-01-06/ff4c4ab3-7bac-430c-bdd1-46cfa5b5f3e2
or these, which are smaller:
https://www.phoenixcontact.com/online/portal/gb?1dmy&urile=wcm%3apath%3a/gben/web/main/products/subcategory_pages/Mini_and_micro_terminal_blocks_P-15-01-10/5ebbe9ed-a249-41bd-ac1c-20313e51a149

You can get accessories which allow several blocks to be commoned-together.
If you were really tight for space I guess you could use a combination of
these, and the lever WAGOs you linked to before (I've used those WAGOs in
the past too :) )

Some alternatives to the Phoenix Contact blocks here too:
http://cpc.farnell.com/webapp/wcs/stores/servlet/Search?st=screw+terminals&catalogId=15002&categoryId=700000031004&langId=69&storeId=10180
and these from Weidmuller:

HTH,
Tim.
