The 3500/22M Transient Data Interface (TDI) is the communication and data-collection hub of the Bently Nevada 3500 Machinery Protection System. Designed for high-reliability industrial environments, this module connects the 3500 rack to plant networks and condition-monitoring software, enabling real-time machinery diagnostics and predictive maintenance.
Manufactured by Bently Nevada, the 3500/22M is widely used in power generation, oil & gas, petrochemical, and heavy industrial applications.
The 3500/22M (Part Number: 138607-01) combines the functionality of a Rack Interface Module and communication processor into a single compact module. It continuously collects steady-state and transient machinery data from all installed 3500 monitor modules and transmits it to supervisory systems.
Installed directly beside the power supply in a 3500 rack, it acts as the primary communication gateway between the monitoring system and external computers or DCS/PLC networks.
