4. Product Introduction
The Bently Nevada 2155-40-01 is the TDISecure Communication Processor with AC power input. It serves as a secure interface that collects high-fidelity vibration and process data from 3300 or 3500 systems and forwards it to System 1 or other host platforms without direct Ethernet exposure of the protection system.
This unit replaces older TDXNet processors with improved data collection rates for both steady-state and transient conditions. In plant environments, it provides the bridge for reliable, protected machinery health data. Confirm exact system compatibility and cybersecurity requirements with the current Bently Nevada documentation before deployment.
