The Bently Nevada 3500/32 is a 4-channel relay module designed for critical machinery protection within the Bently Nevada 3500 monitoring system. This industrial-grade module provides configurable relay outputs for alarm and shutdown functions in turbomachinery, compressors, and other high-value rotating equipment. As part of Bently Nevada’s flagship 3500 series, the 3500/32 integrates seamlessly with vibration monitors and other system components to deliver reliable fault protection in power generation, oil & gas, and heavy industrial applications.
Featuring epoxy-sealed relays rated for 100,000 operations, the Bently Nevada 3500/32 offers exceptional durability in harsh environments (-30°C to +65°C). Each channel supports programmable AND/OR logic for complex voting schemes, while LED indicators provide real-time status monitoring. The module’s fail-safe design and electrical isolation ensure minimal false trips, making it a trusted solution for SIL-2/SIL-3 safety systems.
