QUESTION
Our contractor is proposing to use the BMXDRA1605 (Schneider) DO module for controlling some pumps with an MCC. (Please see below).
From the data sheet i noted that all out puts are supposed to use a power sources with one pole connected together. I think this is not always possible.
I want to know if there are other models with outputs which are truly independent of each other.

It think the BMX DRA 0805 or maybe the BMX DRA 0804T will provide the isolated outputs you want, depending on your voltage requirements.

Typically there are “blocks” that have a common ground or source. You have to work the system to use that feature. Sometimes it doesn’t work well. You can side-step the issue by using the output with whatever source it has to run a relay that provides complete isolation.
