Features:
- Dual Epoxy Construction Ensures Reliable Operation And Enhanced Mechanical Strength.
- Supports Multiple Analog Outputs Including 4-20 mA, 1-5 VDC, And 0 To -10 VDC Signals.
- Single-Pole Double-Throw (SPDT) Relays Provide High-Current Alarm Capabilities.
The 84145-01 module is a specialized terminal board designed to interface seismic and velocity transducers with the 3300 Series monitoring system. Its compact design allows easy mounting on the back of monitoring racks while ensuring secure and accurate signal transmission from input channels.
Equipped with two input channels, the board efficiently routes transducer signals to recorder outputs, supporting multiple analog signal types. This flexibility enables accurate monitoring, data collection, and alarm triggering for industrial machinery in real time.
Engineered for demanding environments, the 84145-01 operates reliably across temperatures from 0°C to +65°C (+32°F to +150°F) and can be stored between -40°C and +85°C (-40°F to +185°F), withstanding relative humidity up to 95% noncondensing. Its robust epoxy construction and versatile relay functionality make it a durable and essential component for vibration and velocity monitoring systems.
The 84145-01 Bently Nevada Seismic Dual Epoxy Relays may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Bently Nevada 84145-01 Seismic Dual Epoxy Relays Specs
General
- Manufacturer GE / Bently Nevada
- Model 84145-01
- Condition New Original ready stock
- Product Family 81546-01,81545-01,81544-01
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.
- Recorder Output: Provides a 4-20 mA or 1-5 VDC analog signal proportional to vibration velocity for remote communication.
- Hardwiring Relay Output: Transmits "Alert" and "Danger" statuses to the host computer or alarm panel via physical contacts.
- Buffered Output: Provides a raw dynamic waveform signal interface for easy connection to an ADRE diagnostic instrument for spectrum analysis.
- Internal Bus Integration: Enables high-speed analog signal interfacing with front-end monitoring modules (such as 3300/55) via the 3300 rack backplane.
- High Contact Reliability: Epoxy-sealed encapsulation effectively prevents contact arcing, enhancing safety in flammable and explosive environments.
- High-current protection interlock: Supports 5A high rated current, directly driving the shutdown solenoid valve, reducing intermediate links and improving system reliability.
- Environmental failure protection: The epoxy layer provides excellent moisture and salt spray protection, preventing false alarms or failures to operate due to environmental corrosion.
- OK status monitoring: The system monitors the sensor circuit in real time; in case of disconnection, it automatically puts the relay into a preset fail-safe state.
- Casing vibration monitoring: Installed on rolling bearing housings where displacement probes cannot be installed, it monitors seismic vibrations of the unit's bearing housing.
- Hydropower generator protection: Utilizing its moisture-proof properties, it is used to monitor low-frequency vibrations of hydro-generator units.
- Cooling tower fan monitoring: Monitors the vibration levels of gearboxes and motors in humid, misty environments.
- Reciprocating machinery protection: Used to monitor large-amplitude impact vibrations of reciprocating compressor bodies.
- Hard-connection retrofit for legacy systems: As a maintenance component for the 3300 system, it reliably connects local vibration protection signals to the plant-wide ESD (Emergency Stop System).
