|
The other day, in the lab, we found interfacing to a Multi-Z buss card to
a "solid state relay Cell I/O" might be hazardous to your health. The rating is 240 VAC but the "track to track" spacing going to the terminal block connector is only 0.10 inch spacing. This printed circuit board layout mistake could cause arc-over and shorts if you use this module at 240 VAC. Be forewarned.
