Safe-off board - Whats the purpose?
Safe-off board - Whats the purpose?
(OP)
When I use a contactor monitoring circuit, then I pretty much know when the drive (VFD or servo drives) is powered, right? Then why do we have to buy the additional safe-off board (especially to the Powerflex Allen-Bradley drives)? Whats the purpose? Is it to get an additional safety certificate level??

I find too much redundancy in this logic, but I guess you are right that this is a requirement for a higher safety category level.
