The BENTLY 3500/22M 288055-01 is the most advanced version of the Transient Data Interface for the 3500 rack. While standard monitors provide overall vibration values, the TDI captures "transient" data—the high-resolution waveforms that occur during machine startups, shutdowns, and sudden events. The 288055-01 hardware is optimized for high throughput, ensuring that data from all modules in the rack is synchronized and transmitted without loss.
The primary purpose of the 288055-01 is to act as the bridge to Bently Nevada System 1 software. It allows diagnostic engineers to perform root cause analysis by viewing orbits, spectrums, and shaft centerlines. The enhanced processing power of the 288055-01 ensures that even in racks with high point counts, the diagnostic software receives steady, real-time updates of machinery health.

The 3500/22M 288055-01 supports Ethernet and serial communication. It manages the rack-level Modbus mapping, allowing the 3500 system to communicate status and measurement data to the plant’s DCS or PLC. This dual-role (diagnostics via Ethernet and protection status via Modbus) makes the 3500/22M a central piece of any modern industrial automation architecture.
Beyond data acquisition, the TDI is the central point for rack configuration. Engineers connect to the 288055-01 using the 3500 Rack Configuration Software to set alarm levels, relay logic, and transducer parameters. This module stores the configuration settings for the entire rack, providing a centralized and secure management interface for the machinery protection system.
The 288055-01 is designed for maximum uptime. It performs continuous self-tests to ensure its own internal circuits and communication ports are functioning correctly. In mission-critical applications, the 3500 system supports redundant TDIs, ensuring that the plant never loses visibility of its most critical rotating assets even if a communication module requires service.
