24VDC power supply to DeltaV 8 wide carrier module

I would like to know if it is possible to power via different feeds the 2 wide carrier (for a 24VDC power supply feed + MX controller) and an 8 wide carrier (output side) mounted on the same rail.

The goal is to cut field power via a safety relay when predefined conditions are triggered then bringing all the field devices in a safety position.

I need my controller to stay up in order to also trigger a safety logic in parallel to the hardwired one.

Regards,

  • You can have separate 24 VDC power feed to the 2-wide and the field power connections on the 8-wide, in fact this is recommended to prevent noise from field power to cause any issues with the supply to the controller and system power supply. Please make sure you follow the site installation guides.
