RS485/422 Isolated Network

Feb 22, 2008 2 Replies

Hello All, Could you validate the following assumption(s) on isolated network implementation


1) An isolated RS485/422 Comport can connect to the none- isolated network.


2) Having more than one isolated comport will require a separate isolated power source for each of the isolated transceivers



I am new to the isolated design, I would appreciate any feedback or reference.



Regards, Babak


Sure.

Yep, if you have a common PS then you're not isolated, or if the power source does not provide isolation you're not isolated. Our isolated RS-485 products all have an on board DC-DC converter to run the ports.

All,

Thanks Jim!
