The Bently Nevada 3500/50 TMR Tachometer I/O Module is a triple‑modular‑redundant speed and phase interface designed for the highest levels of machinery protection reliability. Built for use in TMR‑configured 3500 racks, this module processes rotational speed and phase reference signals from compatible transducers and distributes validated data to the protection system using redundant voting logic.
Installation: Standard 3500 rack slot with TMR configuration

FAQ
Q: What makes the TMR version different from the standard 3500/50 module A: The TMR version uses triple‑modular‑redundant architecture for fault‑tolerant speed and phase monitoring.
Q: Which sensors are compatible with the TMR module A: It supports proximity probes, magnetic pickups, and Keyphasor‑type transducers.
Q: Is the TMR module required for all 3500 racks A: No, it is required only for racks configured for TMR protection.
