Flexible Logic Configuration: Each relay can execute AND/OR logic across multiple monitor channels, enabling customized safety interlocks.
Space-Saving Design: Four channels in a single module optimize rack space compared to 8–12-channel alternatives.
High Reliability: Epoxy-sealed construction resists vibration, dust, and EMI/RFI interference.
Safety Compliance: Supports SIL 2-rated systems and hazardous area certifications (e.g., ATEX/IECEx) with voltage restrictions.
Case Study: A U.S. power plant reduced generator downtime by 20% using the 3500/32 to trigger cooling system shutdowns during excessive vibration events.
The BENTLY NEVADA 3500/32 is a compact, full-height relay output module designed for the 3500 Machinery Monitoring System. It provides four independent, user-programmable relay outputs for critical machinery protection, triggering alarms, shutdowns, or control actions based on configurable logic (AND/OR). Ideal for harsh industrial environments, the module supports applications in power generation, petrochemical, and manufacturing sectors, ensuring reliable operation and reduced downtime.
