Bently Nevada 125840-01 High Voltage ac Power Input Module (PIM)
The Bently Nevada 125840-01 is a precision i/o module for the Bently Nevada 3500 Series machinery protection platform. Manufacturer: Bently Nevada | Availability: In Stock | Operating Temperature: -30 to +65 degrees Celsius. Factory-sealed, fully tested on a live 3500 rack with 48-hour burn-in at 55°C. 12-month warranty. Ships within 24 hours from Shenzhen.
Technical Specifications
| 125840-01 is an AC Power Input Module | developed by Bently Nevada. This system's Power Supplies are half-height modules designed for installation in specific slots on the left side of the rack. The rack is capable of housing one or two power supplies (in any combination of AC and/or DC), with either supply being sufficient to power the entire rack. If a second supply is installed, it serves as a backup for the primary supply. |

Detailed Product Information
ðŊ System Integration
The Bently Nevada 125840-01 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.
