Has anyone seen relay blocks like this (G6B-4CB)? I am retrofitting an old machine with new drives and it appears to me that the two blocks on the left aren't being used....since I don't see but 0V wires terminated at the bottoms of these. They run from this relay to an I/O connection board (also Omron), that then connects to the I/O port of an MC421. Thanks
