🎯 Critical Applications

Emergency Shutdown Systems (ESD): Interface vibration monitors and protection systems with plant-wide ESD logic, providing fail-safe relay contacts that trigger turbine trips, valve closures, and process shutdowns when dangerous conditions are detected.

Alarm Annunciation: Drive visual and audible alarm panels in control rooms, alerting operators to developing machinery problems before they escalate into failures. Multiple modules can create prioritized alarm hierarchies.

PLC/DCS Integration: Bridge the gap between Bently Nevada monitoring systems and programmable logic controllers or distributed control systems that require dry contact inputs for machinery status.

Redundant Protection: Implement voting logic and backup protection schemes by combining multiple relay modules with different trip setpoints or measurement parameters.

⚡ Design Features

✅ Fail-Safe Operation: De-energize-to-trip design ensures protection even during power loss
✅ High Isolation: 1500V isolation protects sensitive monitoring circuits from high-voltage faults
✅ Gold-Plated Contacts: Reliable switching of low-level signals without contact degradation
✅ Visual Diagnostics: Front-panel LEDs confirm power and relay state at a glance
✅ Industrial Construction: Conformal-coated PCB resists moisture, dust, and chemical exposure

🔧 Installation Advantages

The 82926-01 mounts directly on standard 35mm DIN rail, simplifying panel integration and reducing installation time. Screw-terminal connections accept 12-22 AWG wire, accommodating both control cabinet wiring and field cable terminations.

Compact footprint allows high-density installations—critical when panel space is limited. The module's low power consumption means multiple units can share common power supplies without oversizing.

🛡️ Safety & Reliability

Designed to API 670 and IEC 61508 safety standards, this relay module meets the stringent requirements of machinery protection systems in oil & gas, power generation, and chemical processing facilities. The fail-safe design philosophy ensures that any internal fault results in a safe trip condition rather than a dangerous undetected failure.

Field-proven reliability across millions of operating hours in the harshest industrial environments—from offshore platforms to desert refineries to arctic gas plants.
