1. Product overview
   Bently Nevada 330130-045-00-00 is a special extension cable for 3300x8mm proximity sensor system, which is used to connect 3300x8mm probe and Proximitor sensor to ensure high-precision vibration and position measurement signal transmission. The cable adopts optimized electrical and mechanical design and is suitable for industrial machinery condition monitoring applications, such as turbines, compressors, pumps and motors.
2. Main technical features
   (1) High performance electrical characteristics
   Low-resistance design: the typical value of the center conductor resistance (RCORE) is 0.88 Ω 0.13 Ω (4m in length), ensuring low-loss signal transmission.
   Shielding and anti-interference: 75Ω triaxial cable structure and fluorinated ethylene propylene (FEP) insulation layer are adopted to effectively suppress electromagnetic interference (EMI) and radio frequency interference (RFI).
   Compatibility: It is completely matched with 3300 XL 8mm probe and Proximitor sensor, supporting plug and play without additional calibration.
   (2) Strong and durable mechanical structure
   High tensile strength: CableLoc patented design can bear a tensile force of 330N(75lbf) to prevent the cable from accidentally falling off.
   Anti-oil and anti-corrosion: Optional FluidLoc version, to prevent oil from penetrating into the cable, suitable for lubricating oil or coolant environment.
   Gold-plated ClickLoc connector: corrosion-resistant, oxidation-resistant, reliable connection can be ensured only by finger tightening, and it has locking mechanism.
   (3) Environmental adaptability
   Standard temperature range:-52 C to+177 C (-62 F to+350 F), suitable for most industrial environments.
   Extended temperature range (ETR) option: Up to 260 C (500 F), suitable for high temperature applications (such as gas turbine exhaust section).
   Minimum bending radius: 25.4mm(1 inch), easy to install in narrow space.
3. Typical application
   Vibration monitoring of rotating machinery (API 670 standard application)
   Axial and radial position measurement (such as turbine shaft displacement)
   Keyphasor® speed signal acquisition
   Mechanical monitoring in high temperature or oily environment
   Step 4 summarize
   Bently Nevada 330130-045-00-00 3300XL extension cable has become the key component of industrial machinery condition monitoring system because of its low resistance, anti-interference, high mechanical strength and wide temperature adaptability. Its modular design supports rapid replacement, ensures long-term stable operation of the system, and is suitable for harsh working conditions in petroleum, chemical, electric power, shipbuilding and other industries.

1. Module overview
   125840-02 is a Low Voltage AC power input module (PIM) in Bently Nevada 3500 series mechanical protection system, which belongs to the Legacy power solution of this system. This module needs to be used together with the supporting Legacy low-voltage AC power supply module to provide power support for the 3500 rack.

Key characteristics
Traditional system components: It belongs to the early power supply solution of Bently Nevada and is incompatible with the new Universal AC power supply system.
Dedicated voltage input: designed for a specific low-voltage AC input range (refer to the specific specifications, and the parameters of this model are not clearly listed in the document).
Safety protection: built-in overvoltage protection mechanism, abnormal voltage will trigger PIM fuse to open.
Modular architecture: the standard half-height module size (120.7mm×25.4mm×114.3mm) is adopted.

2. Technical parameters (inference)
   Note: The original document did not directly list the parameters of 125840-02, and the following is inferred based on similar Legacy modules.

Possible specifications of parameter categories (refer to Legacy Low Voltage DC analogy)
The input voltage is expected to be in the range of 20-30Vac (official confirmation is required).
The fuse specification may use 01720045 5A/500V fast-melting fuse.
Installation position 3500 Half-height slot on the left side of rack
Environmental adaptive working temperature-30 C to+65 C.

106m1081-01 universal AC power input module (PIM) is one of the core components of Bentley Nevada 3500/15 AC and DC power supply system, which is specially designed for universal AC voltage input. The module is used in conjunction with general AC power supply to provide stable and reliable power input support for 3500 series mechanical protection system.
Key features
Wide voltage input range: support 85–264 VAC RMS (non-hazardous area) and 85–250 VAC RMS (hazardous area), and adapt to different global power grid standards.
High compatibility: it is compatible with the new universal AC power supply, but not with the traditional high/low voltage AC PIM.
Safety protection: Built-in overvoltage protection mechanism, PIM fuse will be disconnected when overvoltage occurs to avoid equipment damage.
Modular design: adopt standard half-height module size, which is convenient for installation and maintenance.
