Bently Nevada 3500/33M 16-Channel Relay Module – 3500 Series Machinery Protection System
When a critical relay output fails in a turbine protection rack, the consequences are immediate and severe: unplanned shutdowns, cascading equipment damage, and production losses that can reach tens of thousands of dollars per hour. In high-stakes rotating machinery environments — power generation, oil & gas, petrochemical — the relay module is the final line of defense between a vibration alarm and a catastrophic mechanical failure. Without a reliable, fully functional relay output module, your entire protection system is compromised.
The Bently Nevada 3500/33M is a 16-channel relay output module engineered specifically for the 3500 Series Machinery Protection System — one of the most widely deployed vibration monitoring platforms in global industrial automation. As a high-density relay module, the 3500/33M consolidates alarm and trip relay outputs into a single rack slot, making it the preferred choice for engineers who demand both channel density and system reliability in mission-critical monitoring applications worldwide.
