Flexible Logic Configuration: Each relay can be programmed independently to execute AND/OR logic across multiple monitor channels, enabling complex safety interlocks.
High Reliability: Epoxy-sealed design resists vibration, dust, and EMI/RFI interference, ensuring long-term performance in extreme conditions.
Redundancy Support: Works with redundant power supplies (e.g., 3500/15) and monitors for SIL-rated safety systems.
Case Study: A petrochemical plant reduced compressor failures by 30% using the 3500/33 to trigger shutdowns when dual vibration monitors exceeded thresholds.
The BENTLY NEVADA 3500/33 is a full-height relay output module designed for BENTLY’s 3500 Machinery Monitoring System, providing 16 independent, user-programmable relay outputs for critical machinery protection. It interfaces with vibration, speed, and temperature monitors (e.g., 3500/42M, 3500/53) to trigger alarms, shutdowns, or control actions based on configurable logic (AND/OR). The module ensures reliable operation in harsh industrial environments, supporting applications in power generation, petrochemical, and manufacturing sectors.
