I want to install an Rx3i. Some of the cards require 24VDC power, the relay output, DIs, and Analog Inputs.
There is a 24 VDC input for an external isolated power supply.
I am using the multipurpose P/S modules in parallel, they don't have a 24VDC output so I will have to connect directly to the backplane.
Can I power the P/S modules and the External Supply input from the same DC Power Supply, I realize the potential for voltage drop due to relay coil inrush but I will only energize one at time and the supply is quite robust.
I couldn't find anywhere in the manual where it forbids this, it only mentions "Isolated," isolated from what?
Also, Floating DC power is what is available for DC distribution.
Thanks,
I hope you can help me out.
