🛡️ Protection System Role

Machinery Shutdown Logic: When vibration exceeds safe limits, this module triggers emergency stop sequences, preventing catastrophic equipment damage in turbines, compressors, and generators.

Alarm Annunciation: Dual setpoints enable both warning and danger alarms—operators receive early notification at the alert level, with automatic shutdown at the trip level.

PLC/DCS Integration: Relay contacts interface directly with plant control systems, enabling coordinated responses across multiple protection layers without requiring analog input cards.

🔍 Real-World Deployment

Power Generation: Steam turbine protection systems use these modules to monitor bearing vibration across multiple measurement points, with relay outputs feeding into turbine control panels for coordinated trip logic.

Oil & Gas: Compressor stations deploy these modules in redundant configurations—if any bearing exceeds vibration limits, the relay triggers gas isolation valves and initiates controlled shutdown sequences.

Chemical Processing: Pump protection systems combine vibration and temperature monitoring, with relay modules providing hardwired interlocks that override process control during emergency conditions.

✅ Engineering Benefits

✓ Dual Setpoints: Independent alert and danger thresholds with separate relay outputs
✓ Visual Feedback: Front-panel LEDs confirm power, OK status, and alarm states
✓ Field Adjustable: Setpoints and hysteresis configurable without tools or programming
✓ Failsafe Design: Relay de-energizes on alarm condition (normally energized logic)
✓ High Contact Rating: Directly switches solenoid valves and motor starters
✓ Isolated Outputs: Relay contacts electrically isolated from input circuits

🔧 Installation Simplicity

The module accepts standard proximitor outputs via screw terminals, with clearly labeled connections for power, input signal, and relay contacts. Front-panel test buttons allow functional verification without disconnecting field wiring. Removable terminal blocks enable module replacement without rewiring.

📊 System Architecture

Typically deployed downstream of 3300 XL proximitors, this module completes the measurement chain from probe to protective action. Multiple modules can share common power supplies and alarm buses, simplifying multi-channel protection systems. Compatible with all Bently Nevada 8mm proximity probes and 3300 series proximitors.
