Machinery Protection Solution – Bently Nevada 3500/32 | 3500 Series
The Bently Nevada 3500/32 4-Channel Relay Module is a critical output interface within the 3500 Series Machinery Protection System (MPS). Designed for continuous, high-reliability industrial environments, this module converts monitored machinery data into discrete relay outputs that trigger alarms, shutdowns, and safety interlocks across rotating equipment installations.
Where This Product Is Used
The 3500/32 is specified by reliability engineers and control system integrators across the following industries and applications:
- Oil & Gas: Compressor trains, gas turbines, centrifugal pumps on offshore platforms and onshore processing facilities
- Power Generation: Steam turbine protection, generator bearing monitoring, and boiler feed pump trip circuits
- Petrochemical & Refining: Reactor agitator protection, column overhead compressors, and critical rotating machinery SIS integration
- LNG & Pipeline: Booster compressor stations requiring API 670-compliant relay output modules
- Marine & Heavy Industry: Propulsion shaft monitoring and large industrial fan protection systems
