Product Introduction & Positioning

The BENTLY 3500-22M 288055-01 is a standard transient data interface module within the trusted Bently Nevada 3500 Series condition monitoring system. It functions as a central data capture device, collecting high-speed transient waveform data from multiple sensors attached to critical machinery. This module supports data sampling for up to 48 channels, delivering comprehensive vibration and process data that facilitate precise fault detection and early warning diagnostics. As part of the 3500 Series architecture, the 3500-22M is designed for modular rack installation where it communicates with other system modules and external software over Ethernet or fiber optic connections using the BN TDI protocol. Engineers value it for its compatibility with firmware and the latest diagnostic tools that help streamline analysis of transient machinery events. This module’s ability to interface reliably with the System 1™ software makes it a core component for monitoring asset health in applications where downtime reduction and machine reliability are paramount.

Key Technical Features & Functional Benefits

The BENTLY 3500-22M 288055-01 stands out for its high-speed data acquisition capabilities, supporting transient waveform capture from up to 48 input channels simultaneously. It offers robust communication options through autosensing 10Base-T/100Base-TX Ethernet ports and 100Base-FX fiber optic interfaces, ensuring low latency and secure data transfer over distances up to 2000 meters using multimode fiber. This flexibility enables it to integrate into large-scale distributed monitoring systems with minimal signal degradation.

Energy efficiency is a hallmark of the module, consuming just 10.5 watts under typical operating conditions. The module features multiple front panel LED indicators to provide real-time status on communication, rack health, configuration validity, and trip multiply modes, which simplify local troubleshooting and maintenance. The embedded relay output lets users configure open or closed contacts for fault or normal operation signaling, facilitating alarm management within complex control architectures.

Engineered for durability, the BENTLY 3500-22M 288055-01 operates over a broad temperature range from -30°C to +65°C (-22°F to +149°F), suitable for harsh industrial conditions. It also boasts extended battery life estimates—38 years powered and 12 years unpowered at 50°C—making it reliable for long-term deployment in critical machine monitoring applications. The module’s compact dimensions and moderate weight ease installation in standard 3500 rack configurations while maintaining ruggedness under vibration and electrical noise exposure.

Installation Notes & Maintenance Best Practices

Installing the BENTLY 3500-22M 288055-01 requires sufficient rack space, as it occupies a full-height slot in the 3500 Series rack. Careful attention to grounding and electromagnetic shielding is essential to maintain signal integrity in electrically noisy industrial environments. Ethernet and fiber optic cable lengths should be planned to stay within maximum ratings (100 meters for Ethernet and 2000 meters for fiber optic) to prevent communication errors. The module’s front panel USB port facilitates easy configuration and diagnostics, but must be shielded properly to avoid accidental disconnection during operations.

Routine maintenance includes visually inspecting LED status indicators to quickly identify faults or alarm states. Periodic firmware updates and configuration backups via the USB port or Ethernet interface help maintain compatibility with the latest System 1™ diagnostic features. Scheduled checks of fiber optic connectors and cables ensure reliable long-distance data transmission. Fault relay outputs should be connected to alarm systems and tested regularly to confirm correct operation, supporting proactive maintenance strategies that minimize downtime risk.
