The Bently Nevada 3500/22M Transient Data Interface (TDI) serves as the primary gateway between the 3500 Monitoring System and System 1™ configuration and diagnostics software. Unlike standard interface modules, the 22M TDI provides advanced transient data acquisition, capturing critical high-resolution dynamic waveforms during turbine start-up, coast-down, or unexpected machine trips. It integrates the functions of a 3500/20 Rack Interface Module (RIM) with the data collection capability of external processors, supporting Ethernet-based communication and M-series hardware architecture. The 3500/22M is essential for Condition Monitoring, providing synchronized vibration data across all channels for polar plots, Bode plots, and shaft centerline analysis. Our stock includes various 3500/22M configurations, including redundant TMR versions and units with internal/external termination options, ensuring your rotating machinery protection system maintains continuous, high-fidelity data connectivity for predictive maintenance and fault diagnostics.
