Product Description
The Bently Nevada 3500/22M with PWA 138607-01 S is the “brain” of the 3500 Machinery Protection System’s communication architecture. The TDI acts as the primary interface between the monitoring rack and Bently Nevada’s System 1 diagnostic software. The “M” designation and the specific 138607-01 assembly signify its advanced capability to process Transient Data—capturing high-resolution waveforms and spectral data during machine startups, coast-downs, and alarm events. While the monitor modules in the rack handle the critical trip logic, the TDI ensures that every vibration detail is digitized and transmitted for predictive maintenance and root-cause analysis.
Application Fields
This module is mandatory for any 3500 rack integrated with a condition monitoring software platform. It is widely used in power generation (steam/gas turbines), oil and gas (centrifugal compressors), and heavy industrial processing (large motors and fans). It is essential for facilities that require more than just a “shutdown” signal, providing the data necessary for vibration specialists to diagnose shaft misalignment, bearing wear, and mechanical looseness.
Product Specifications
- Weight: 0.90 kg
- Dimensions: 241 mm x 24.4 mm x 163 mm (Standard 3500 Slot width)
- Origin: USA
Operational Precautions
- Slot Placement: The 3500/22M must be installed in the slot immediately to the right of the Rack Power Supplies (Slot 1).
- I/O Module Match: Ensure the front PWA (138607-01) is used with the correct corresponding I/O module (typically the 146031-01 or 147364-01) located at the rear of the rack.
- Firmware Compatibility: When replacing a TDI, verify that the firmware revision is compatible with your current version of 3500 Rack Configuration Software and System 1.
- Data Security: If using the Ethernet port, ensure it is connected to a secure, firewalled industrial network to prevent unauthorized access to machinery trip setpoints.
