Rotating Machinery Condition Monitoring Solution — Allen-Bradley 1440-TB-A | Dynamix 1440 Series
Where This Product Is Used
The Allen-Bradley 1440-TB-A Dynamic Eccentricity Measurement Module is engineered for continuous, real-time monitoring of rotating shaft eccentricity in critical industrial machinery. Typical deployment environments include:
- Power Generation: Steam and gas turbines, generator sets, and hydro turbines where shaft orbit and eccentricity directly impact bearing life and rotor integrity.
- Oil & Gas Processing: Centrifugal compressors, expanders, and high-speed pumps in upstream and downstream facilities requiring API 670-compliant vibration monitoring.
- Pulp & Paper Mills: Large paper machine rolls, dryer cans, and calendar rolls where dynamic runout causes sheet defects and unplanned downtime.
- Steel & Metals: Rolling mill spindles, continuous casters, and hot strip mill drives subject to high radial loads and thermal growth.
- Chemical & Petrochemical Plants: Reactor agitators, large centrifugal fans, and critical pump trains in hazardous-area installations.
- Water & Wastewater: Large vertical turbine pumps and blower trains in municipal infrastructure requiring 24/7 unattended monitoring.

Why Engineers Specify This Model
- Dedicated Eccentricity Algorithm: Unlike general-purpose vibration modules, the 1440-TB-A applies a dedicated eccentricity measurement algorithm that separates dynamic runout from static bow, giving maintenance engineers actionable data rather than raw waveform noise.
- Seamless Rockwell Integration: Native backplane communication with the Dynamix 1440 chassis allows direct data exchange with Studio 5000 / FactoryTalk applications — no gateway or protocol conversion required.
- API 670 Alignment: Measurement architecture follows API 670 (5th Edition) guidelines for machinery protection systems, satisfying insurance and regulatory requirements in oil & gas and power sectors.
- Dual-Channel XY Orbit Capability: Simultaneous XY proximity probe inputs enable full shaft orbit reconstruction, supporting both protection and predictive maintenance use cases in a single module slot.
- Reduced Panel Footprint: Modular Dynamix 1440 architecture consolidates multiple measurement functions into a compact chassis, reducing cabinet space versus discrete relay-based protection systems.
- Long-Term Trend Logging: Integrated with FactoryTalk AssetCentre and Historian for continuous trend storage, enabling ISO 13373-compliant baseline-to-alarm trending over the machine lifecycle.

Application-Specific FAQ
Q: Can the 1440-TB-A be used as a standalone protection device without a DCS or PLC?
A: No. The 1440-TB-A is a chassis-mounted module that requires a Dynamix 1440 chassis and communication module to operate. It is not a standalone relay-output protection device. For standalone protection, consider the Bently Nevada 3500 series.
Q: Is the 1440-TB-A compatible with Bently Nevada 3300 XL proximity probes?
A: Yes. The module accepts standard eddy-current proximity probe signals compatible with the Bently Nevada 3300 XL series, provided the signal range and gap voltage are within specification. Verify probe driver output range before installation.
Q: What is the difference between eccentricity and vibration measurement in this context?
A: Vibration modules measure dynamic displacement at operating speed. The 1440-TB-A specifically measures eccentricity — the static and slow-roll shaft bow — which is critical during turbine startup and coast-down phases when shaft speed is below the first critical speed.
Q: Can this module replace a Bently Nevada 3500/72M eccentricity module?
A: Functionally similar, but the 1440-TB-A is native to the Rockwell/Allen-Bradley ecosystem. If your plant standardizes on Studio 5000 and FactoryTalk, the 1440-TB-A offers tighter integration. Cross-platform replacement requires engineering review of signal compatibility and alarm logic.
Q: Do you supply the full Dynamix 1440 system (chassis + modules)?
A: Yes. Konmask can supply complete Dynamix 1440 systems including chassis, communication modules, measurement modules, and accessories. Contact us with your full BOM for a consolidated quote.
Q: What warranty applies to this module?
A: Konmask provides a 12-month warranty against manufacturing defects from the date of shipment. Warranty claims are processed via RMA with our technical team.
