Features:
- Dual Channels With Independent Control For Simultaneous Alarm Monitoring
- Single-Pole Double-Throw (SPDT) Contacts Fully Sealed With Epoxy Resin
- Built-In Internal Barriers Ensure Safe Signal Isolation From Hazardous Areas
The Bently Nevada 88843-04 Dual Epoxy Relays module is engineered for high-reliability industrial monitoring systems. It integrates dual relay outputs with robust epoxy sealing to withstand dust, moisture, and vibration, providing long-term operational stability in demanding environments.
Each channel is electrically isolated with internal barriers, allowing signals from hazardous areas to be safely processed without interfering with other monitoring channels. The module’s output impedance of 100 Ω and minimum load resistance of 10 kΩ ensures precise and consistent signal switching for critical alarm and control functions.
Designed to operate between 0°C and +65°C (+32°F to +150°F) and to be stored under temperatures from -40°C to +85°C (-40°F to +185°F) with up to 95% non-condensing humidity, the 88843-04 delivers dependable performance across a wide range of industrial conditions. Its dual-channel capability supports flexible system design, reducing the number of modules required for multiple alarm points while maintaining safe, isolated signal pathways.
The 88843-04 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).

- Multi-level Alarm Logic: Simultaneously handles two independent physical outputs: "Alert" and "Danger".
- High-Risk Environment Monitoring: Provides signal isolation and protection in environments with extremely stringent explosion-proof requirements, such as oil refineries and chemical plants.
- Rotating Machinery Protection: Used for tripping due to excessive axial displacement and radial vibration in steam turbines and compressors.
- Critical Asset Interlocking: As a hardware-level closed-loop protection, it can still execute physical disconnection logic when the control system fails.
- System Platform: Specifically designed for use with the Bently Nevada 3300 series monitoring frame.
- Sensor Matching: Compatible with 3300 XL series eddy current probes and corresponding Proximitor preamplifiers.
- Modular Design: Supports hot-swapping within the 3300 system rack (depending on specific rack configuration).
- Logic Integration: Its dual contacts allow for easy connection to the inputs of DCS, PLC, or ESD (Emergency Stop System).
- Intrinsic Safety Certification: Integrates internal barriers, compliant with ATEX/IECEx intrinsically safe circuit standards.
- Industry Protection Standards: Fully compliant with API 670 mechanical protection system requirements for reliability and response time.
- Hazardous Area Classification: Suitable for flammable and explosive environments such as Class I, Div 1, or Zone 0/1.
- Electromagnetic Compatibility: Compliant with CE standards, ensuring no interference with low-voltage signals during relay operation.
