Bently Nevada 106M1081-01 – Overview

Bently 106M1081-01 is a Universal AC Power Input Module (PIM) designed for the Bently Nevada 3500/15 rack power system used in machinery protection and condition monitoring systems.

🔧 Basic Information

Manufacturer: Bently Nevada
Part number: 106M1081-01
Product type: Universal AC Power Input Module
System compatibility: Bently Nevada 3500/15 power supply for 3500 machinery protection racks

This module works together with the Universal AC Power Supply to provide stable power to the entire 3500 monitoring rack.

⚙️ Main Function

The module converts plant AC mains into regulated power rails for the monitoring system and distributes it through the rack backplane.

Key roles:

AC → low-voltage DC/AC conversion
Power distribution to rack modules
Power health monitoring and fault reporting

Typical applications:

Turbine protection systems
Compressors and pumps
Petrochemical and offshore platforms
Industrial rotating equipment monitoring

🔋 Electrical Specifications (Key)

Input

85–264 VAC RMS (global power compatible)
47–63 Hz auto-sensing frequency

Output rails

28 VDC up to 5 A (monitor & barrier bus)
12 VAC up to 1 A (auxiliary loads)

Performance & protection

≥80% efficiency at 50% load
Over-voltage protection with fuse
Short-circuit & overload shutdown
Over-temperature protection
Isolation up to 2 kV AC

🧩 System Installation & Redundancy

Installed on the left side of the 3500 rack.
Rack can use one or two power supplies.
When dual supplies are installed:
- Lower slot = primary
- Upper slot = backup (redundant)

This design ensures high availability and continuous monitoring in critical equipment.

⭐ Key Features

Wide global voltage input range
Hot-pluggable module
Built-in fault detection and LEDs
Compatible with new Universal AC power supply (not legacy AC PIMs)
Designed for hazardous and industrial environments

📌 Summary

The 106M1081-01 is the AC input front-end power module for the Bently Nevada 3500 system. Its job is to safely convert and supply power to the rack, ensuring reliable operation of machinery protection systems in critical industrial environments.
