FAQ for TRICONEX 3351
Q1: What is the difference between 3351 and 3301?
A1: 3351 is an enhanced version with upgraded diagnostic logic and better signal stability for dense analog I/O projects.
Q2: Can 3351 and 3301 be mixed in the same Tricon rack?
A2: Yes, they can coexist in the same rack as long as firmware and chassis version match the system requirement.
Q3: Does 3351 support redundant transmitter connection?
