Features:
- Provides Dual SPDT Relay Outputs For Alarm And Control Signal Integration.
- Epoxy-Sealed Construction Ensures Resistance To Moisture And Industrial Contaminants.
- Operates Reliably Across Wide Temperature And Humidity Ranges.
The 84140-01 module is designed to interface seamlessly with the Bently Nevada 3300 Series system, enabling stable signal routing for monitoring and control applications. Its epoxy-encapsulated design safeguards internal relays against harsh industrial conditions, ensuring consistent operation over time.
This relay module functions with a 24 VDC power supply and accommodates standard environmental requirements, supporting reliable performance in high humidity and variable temperature conditions. Its compact form factor simplifies installation in monitoring racks while maintaining durability.
The dual-relay setup allows simultaneous handling of multiple signals, making the 84140-01 suitable for complex industrial systems that require dependable alarm or control outputs without additional hardware.
The 84140-01 Bently Nevada Dual Epoxy Relays may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Sensor Input (XDUCR): Connects to a seismic vibration sensor or displacement probe to receive raw dynamic signals.
- Relay Contact Output: Provides two independent sets of programmable relay contacts (Alert and Danger) for triggering external alarms or performing safety shutdowns.
- Recorder Output: Provides a 4-20 mA or voltage proportional signal for connection to a DCS, PLC, or chart recorder for trend monitoring.
- Buffered Output: Provides unprocessed raw signals via the front panel or module interface for field diagnostics with portable vibration analyzers.
- API 670 Standard: Designed to comply with the American Petroleum Institute (API) 670 standard, a core industry specification for rotating machinery protection systems worldwide.
- CE Certification: CE marking certified in Europe, ensuring compliance with electromagnetic compatibility (EMC) and safety requirements
- Environmental Rating: Epoxy-sealed relays are suitable for control room or instrument panel installation in non-explosive environments.
- Safety Isolation: When used with safety barriers, it supports the connection of sensors in hazardous areas (see installation manual 88837-01 for details).
- Critical Rotating Machinery Protection: Widely used for vibration monitoring of steam turbines, gas turbines, centrifugal compressors, and large industrial pumps.
- Industrial Safety Interlock: When abnormal vibration or displacement is detected, it enables emergency shutdown (ESD) of machinery via relay output.
- Equipment Condition Diagnosis: Utilizes recorder output and buffered signals for long-term trend analysis to help identify bearing failures, rotor imbalance, or misalignment.
- Legacy System Maintenance and Retrofitting: As the 3300 series is nearing the end of its lifecycle, this module is often used for spare parts replacement in existing facilities or expansion of small monitoring systems.
