Key Features & Advantages
Universal Auto-Ranging Input
Accepts any AC voltage from 85 to 264 Vac without manual configuration, jumpers, or dip-switch adjustments. This “global spare” capability eliminates the need for region-specific inventory, simplifying multinational fleet standardization.
Dual Redundancy & Hot-Swappability
Supports N+1 redundant configuration with automatic seamless failover. The lower slot serves as the primary supply, while the upper slot provides hot-standby backup. Modules can be removed or inserted without system interruption, provided the companion supply remains operational.
Robust Industrial Design
Engineered for extreme industrial environments with wide temperature tolerance, high EMI/RFI immunity, and comprehensive protection against overvoltage, overcurrent, and short-circuit conditions. The half-height form factor maximizes rack space efficiency.
Front-Panel Status Indication
Equipped with Supply OK LED indicators for at-a-glance operational status verification, reducing troubleshooting time and enhancing system visibility.
Seamless 3500 Series Integration
Fully compatible with all modules within the Bently Nevada 3500 Machinery Protection System architecture, ensuring plug-and-play installation and reliable long-term operation.

Application Scenarios
| Industry | Application |
|---|---|
| Power Generation | Turbine, compressor, and generator vibration monitoring systems |
| Oil & Gas / Petrochemical | Critical pump, fan, and rotating equipment protection |
| Steel & Paper | Heavy machinery condition monitoring and predictive maintenance |
| Aerospace | Engine and auxiliary power unit (APU) monitoring systems |
| General Industrial | Any facility requiring continuous 3500 Series machinery protection |
The 106M1081-01 is specifically optimized for high-vibration, high-EMI environments typical of refineries, power plants, and heavy manufacturing facilities where unplanned downtime carries severe economic and safety consequences.

Frequently Asked Questions (FAQ)
Q1: Can the 106M1081-01 accept DC power input? A: No. This module is strictly designed for AC inputs (85–264 Vac). Facilities utilizing 24 Vdc or 125 Vdc sources require a different DC-specific PIM variant.
Q2: Is any manual voltage selection (e.g., 110V vs. 220V) required? A: No. The module is fully auto-ranging and automatically detects and adjusts to any voltage within the 85–264 Vac range without jumpers or dip-switch settings.
Q3: Can I mix a Universal AC PIM with a legacy High Voltage AC unit in the same rack? A: No. Mixing universal and legacy power components in the same rack is not supported and may result in system damage or unplanned shutdowns.
Q4: How does redundancy work if my facility only has one mains power source? A: True redundancy requires each PIM to be connected to a separate, independent AC circuit breaker or uninterruptible power supply (UPS) system. Shared mains sources do not provide protection against upstream power failures.
Q5: What is the significance of the 106M1081-01 part number? A: 106M1081-01 is the specific internal PCBA part number for the Universal AC Power Input Module, distinguishing it from older or DC-input variants within the 3500/15 product family.
Q6: What is the recommended spare parts strategy? A: It is recommended to maintain at least two units in inventory—one as a replacement spare and one to preserve the rack’s full redundancy capability in the event of a primary module failure.
