GE 90-70 IO Conversion
(OP)
Hi All,
We are reviewing options to migrate our existing GE 90-70 I/O modules over the Rx3i I/O modules. While there are several options, the two straight forward ones are: 1) Use the Rx3i Conversation Rack and Adaptors to act as a bridge between our existing 90-70 field wiring and the new Rx3i modules, OR 2) Completely replace all 90-70 racks, modules and field wiring with equivalent Rx3i mdoules and accessories.
(Just FYI if you haven't seen option #1 then you can watch a YouTube video here.)
The quick and easy way is option #1, but I am worried about long term maintenance and future I/O expansion efforts might be more problematic with this kit. Option #2 would require more planning, engineering, labor and coordination efforts with Operations (this is a production system), but I see it as a solid, long term solution.
Has anyone here performed a 90-70 migration? If so, what option(s) did you pursue and what were your experiences?
Thanks in advance.

RE: GE 90-70 IO Conversion
I do not see much choice with labor the way it is today. :)
What this does is eliminate the labor of wiring all of the RX3i replacement I/O modules and then troubleshooting proper termination.
You will still need to verify that there is an equivalent RX3i module for each 90-70 module displaced.
