We agree and for the CP270 you can buy:

*         FBM 208 Redundant 0 to 20 mA 4 In 4 Out with Output Readback

*         FBM 240 Redundant Relay Output with Output Readback

Yes, but that turns it into yet another implementation detail to be handled
by the end suer/designer/integrator. 

It would seem like a nice thing to have in (future) FBM's to me.
