Detailed Product Information
ðŊ System Integration
The Bently Nevada 126648-01 connects the 3500 rack to plant condition monitoring and historian infrastructure, streaming real-time vibration and temperature data to System 1, OSIsoft PI, or DCS via Modbus TCP.
Network Options
- Copper (146031-01): 10/100Base-TX, max 100m.
- Fiber (146031-02): 100Base-FX, max 2km â ideal for long runs or high-EMI areas.
Configuration
Static IP mandatory â DHCP expiry causes data gaps. Configure NTP for accurate timestamps. Allow TCP 3500 + TCP 502 through OT firewall.

â FAQ
Q: Copper or fiber?
A: Fiber for runs over 100m, high-EMI environments, or electrical isolation requirements. Copper for standard control room under 100m.
Q: Does replacement require reconfiguration?
A: Yes â IP settings are stored on the module. Document your settings before removing the old module.
ð° ROI
The TDI module enables predictive maintenance. One avoided bearing failure on a 50 MW turbine saves $250K-500K. Without it, your 3500 rack is just a trip system.
