Bently Nevada 81544-01 Spare Relay Module Assemblies (No Relays) Specs
General
- Manufacturer GE / Bently Nevada
- Model 81544-01
- Condition New Original ready stock
- Product Family 3300/16,126648-01,126640-01
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.
- Signal Isolation: Provides initial electrical isolation between the sensor input and the frame power supply, preventing external electromagnetic interference from affecting the monitor's core circuitry.
- Intrinsically Safe Compatibility: When used with Bently Nevada safety barriers, it meets explosion-proof requirements for hazardous areas.
- Fault Monitoring: Supports sensor OK status detection. In the event of a sensor circuit open or short circuit, the module ensures the monitor identifies and locks the alarm, preventing false tripping.
- Passive Design Risk Mitigation: Since this version (No Relays) does not contain physical relays, it eliminates the risk of unauthorized mechanical shutdown due to relay contact sticking or malfunction.
- High Linearity Output: The recorder output (4-20mA or 1-5Vdc) has extremely high linearity accuracy, ensuring that the value transmitted to the DCS/PLC is completely synchronized with the monitor's display value.
- Wideband Response: The buffered output interface enables lossless transmission of high-frequency vibration waveforms, supporting analysis bandwidths up to 10kHz.
- Multi-Range Switching: Internal adjustable jumpers allow users to quickly switch the output signal between 4-20mA, 1-5Vdc, or 0-10Vdc as needed.
- Environmental Tolerance: The circuit board is coated with anti-corrosion paint, enabling long-term stable operation in industrial high-temperature environments ranging from 0°C to +65°C.
- DCS/PLC Logic Control: When the factory's interlocking trip logic is handled by the backend DCS or PLC, the 81544-01 only handles signal transmission, saving hardware costs.
- Centralized Alarm System: With the 3300/10 dedicated relay module already equipped within the 3300 framework, individual channels do not require their own relays; this module is used as a standard interface.
- Dynamic Equipment Condition Monitoring: Specifically designed for the physical input of radial vibration, axial displacement, or keyphasor signals for rotating machinery (such as steam turbines, compressors, and fans).
- Legacy System Spare Part Replacement: Serves as a standard maintenance spare part for the 3300 series (discontinued but widely in service), used to replace older modules damaged by terminal corrosion or aging of analog circuits.
