RTD Temperature spikes
(OP)
Has anyone found a way to eliminate temperature spikes on motor RTD's to keep from tripping out motor protection relay. The relay has no way to add a time delay to filter out spikes.

It sounds to me like you have some electrical noise. Buy some shielded cable. It's more expensive, but worth it in my opinion.
RE: RTD Temperature spikes
We have shielded cable with it grounded at the URTD II module input as directed by the manufactuer. It is floating at the motor side ( The Shield).
