Bently Nevada 133300-01 (3500/15-04) Low Voltage DC PIM — Genuine OEM Power Input Module, New Surplus

Brand Bently Nevada

Model Bently 133300-01 (3500/15-04)

Product Overview

The Bently Nevada 133300-01 is the dedicated Low Voltage DC Power Input Module (PIM) that forms the rear-termination and input-protection stage of the Bently Nevada 3500/15 power supply within the 3500 Series Machinery Protection and Condition Monitoring System. Positioned directly behind the 3500/15 front power-supply module, the Bently Nevada 133300-01 provides the physical interface between the field-supplied low-voltage DC source—nominally 20 to 30 VDC—and the power-conversion circuitry that generates the regulated internal voltages used by every other module in the 3500 rack.

As a half-height rear module, the Bently Nevada 133300-01 mounts in the dedicated left-side power slots of the 3500 rack and carries the external DC feed through a heavy-duty terminal block, input filtering, transient and over-voltage protection, and the backplane connection to the associated 3500/15 supply. Its core value lies in conditioning and safeguarding the incoming primary power: an under-voltage condition does not damage the supply or the PIM, while an over-voltage event causes the integrated fuse on the PIM to open, protecting both the power supply and all downstream monitoring modules. This input stage is fundamental to the 3500 system’s reputation for continuous, unattended protection of turbines, compressors, pumps, and other critical rotating assets.

Designed for high-reliability operation, the Bently Nevada 133300-01 supports fully redundant power configurations. When a second supply/PIM is installed, the lower slot acts as primary and the upper as backup; either module can be removed or inserted without disrupting rack operation, provided the companion supply remains energized. Compliant with the environmental and safety requirements expected of API 670-class machinery protection platforms, the Bently Nevada 133300-01 ensures that clean, stable, and protected DC power is always available to vibration monitors, Keyphasor/tachometer modules, I/O modules, communication gateways, and relay modules—making it an indispensable spare for maintaining continuous machinery protection.

Main Features and Advantages

Precision-matched LVDC input stage: The Bently Nevada 133300-01 is purpose-engineered for the 20–30 VDC low-voltage DC variant of the 3500/15 supply. This tight voltage window matches common industrial 24 VDC UPS and DC distribution feeds, allowing the 3500 rack to be powered from the same reliable DC source that supplies field instrumentation and safety systems—without the need for a separate AC distribution circuit.

Integrated over-voltage and transient protection: A defining strength of the Bently Nevada 133300-01 is its fault-isolation behavior. While input under-voltage is tolerated without harm, any over-voltage condition causes the PIM’s onboard fuse to open, immediately protecting the 3500/15 converter and every downstream rack module from catastrophic damage. This single-point protective function makes the PIM a true safeguarding component, not merely a wiring convenience. The specified replacement fuse is 01720045, ensuring a controlled and documented repair.

Redundancy and hot-swap for continuous availability: The 3500 rack accommodates one or two power supplies in any AC/DC combination, and the Bently Nevada 133300-01 is the PIM half of each LVDC pair. In a dual-supply arrangement, the lower slot is primary and the upper is backup; with both installed, either supply/PIM can be removed or inserted without interrupting rack operation. This is critical during maintenance on live protection systems, where even a momentary power loss could trigger a machine trip.

Rugged industrial construction: The Bently Nevada 133300-01 uses heavy-duty terminal-block connections designed to withstand the sustained vibration of compressor, turbine, and rotating-equipment installations. Its passive, convection-cooled design is optimized for continuous rack operation, while the half-height form factor preserves rack space for monitoring and I/O modules. The module’s environmental ratings—wide operating/storage temperature range and 95% non-condensing humidity tolerance—match the rest of the 3500 family, supporting deployment in harsh plant environments.

Hazardous-area and regulatory compliance: Depending on the agency-approval option selected (00 = none, 01 = CSA/NRTL/C), the Bently Nevada 133300-01 supports installations in Class I, Division 2 / Zone 2 hazardous areas, with ATEX/IECEx certification available. This makes it suitable for oil & gas, petrochemical, and refining applications where explosion-protected equipment is mandatory.

Interchangeability note: The Bently Nevada 133300-01 is the LVDC (20–30 VDC) PIM. It is electrically and mechanically incompatible with the Legacy 3500 High Voltage DC PIM, High/Low Voltage AC PIM, and the universal AC PIM family. Likewise, it must not be substituted for high-voltage DC (88–140 VDC) or AC-input modules—applying the wrong input voltage will destroy the module. Always verify the “04” low-voltage DC designation on the host 3500/15 front supply before installation.
