1771-OFE innards

Kind of crazy they can cram the same technology into point I/O modules. Had to take this guy apart today to move jumpers to change it from -10vdc to 10 vdc range to 0vdc to 10vdc for a system upgrade.

Really made me think how convenient new stuff is. Those jumpers are a mouse click in studio 5000. Was a fun experience today working with some old reliable tech mixing with new stuff. This module might be as old as me.
