Product Description

Fault-Tolerant Protection for Critical Assets

The 3500/34 (Model: 3500/34) is a high-integrity Triple Modular Redundant (TMR) relay module designed for the Bently Nevada 3500 Series Machinery Protection System. Unlike standard relay modules, the 3500/34 (Model: 3500/34) utilizes a redundant architecture to provide the highest level of reliability for emergency shutdown (ESD) applications. It performs automatic fault detection and isolation, ensuring that a single component failure within the module does not result in a loss of protection or an accidental machinery trip. This makes it the industry standard for high-stakes environments involving large turbines, compressors, and generators where uptime is mission-critical.
