Product Description

The 3500/22M (161580-01) is a high-performance Transient Data Interface (TDI) module that serves as the primary communication link between the Bently Nevada 3500 rack and System 1 condition monitoring software. It is specifically engineered to capture and process both static data and high-resolution dynamic waveforms, making it indispensable for advanced machinery diagnostics and transient event analysis during machine start-ups or shutdowns.

Unlike standard rack interface modules, the 3500/22M (161580-01) features integrated Keyphasor signal processing capabilities, allowing it to support up to four Keyphasor signals per rack. It continuously monitors the health of the 3500 system and provides an "OK" relay output to signal rack integrity. While the module is not used for primary machine protection (tripping), it is the essential gateway for the deep-dive data required for predictive maintenance and root cause analysis.
