Bently Nevada’s current 3500/15 documentation lists 114M5335-01 as the Low Voltage DC Power Input Module, while 114M5330-01 is the corresponding Low Voltage DC Power Supply. The PIM and power-supply module are separate components.

 

Product Introduction

Bently Nevada 3500/15 114M5335-01

The Bently Nevada 3500/15 114M5335-01 is the Low Voltage DC Power Input Module used with the 3500/15 low-voltage DC power-supply arrangement. It accepts a 20–30 VDC external supply and interfaces that source to the associated 3500/15 power-supply module.

This is a rack-power component, not a monitoring or communication card. Its importance is simple: the 3500 rack depends on the power-supply assembly to provide the required internal operating voltages. For plants using a 24 VDC control or UPS distribution system, the low-voltage DC configuration allows the machinery protection rack to be powered directly from that DC source.

Application Scenarios & Field Pitfalls

Engineering Pain Point

A 3500 rack can have perfectly healthy monitor modules and still be completely unavailable because its power input hardware has failed. This is especially relevant in plants using 24 VDC UPS-backed instrumentation power. The 114M5335-01 sits at the front of that power path, so replacing it requires more than checking whether the module physically fits.

Typical Applications

  • Power Generation — 24 VDC or UPS-backed power distribution for turbine and generator machinery-protection racks.
  • Oil & Gas — Low-voltage DC power feeds for compressor, turbine, and rotating-equipment monitoring systems.
  • Petrochemical — 24 VDC instrument-power systems supplying 3500 machinery protection cabinets.
  • Industrial Process Plants — Legacy 3500 racks where DC control power is preferred over AC input for improved integration with plant UPS systems.

Technical Pitfalls to Avoid

  1. Do not confuse the PIM with the power-supply module.
    This is the key procurement issue. 114M5335-01 is the Low Voltage DC PIM; 114M5330-01 is the associated Low Voltage DC Power Supply. They work together but are separate replaceable parts.
  2. Verify the actual DC source voltage.
    The low-voltage DC configuration is specified for 20–30 VDC. A nominal “24 VDC” plant supply is normally within that range, but measure the actual voltage at the rack input, particularly on long cable runs or battery-backed systems.
  3. Check whether the rack uses one or two supplies.
    A 3500 rack can contain one or two power supplies. When two are installed, the lower supply is primary and the upper supply is backup. The two supplies can also use separate source voltages.
  4. Do not mix legacy and current DC power-supply families casually.
    Bently Nevada explicitly identifies compatibility limitations between the current 3500/15 DC power supplies/PIMs and legacy DC power-supply assemblies. Verify the complete power-supply generation before replacing individual components.
  5. Check the PIM fuse and upstream wiring.
    A blown fuse can be the symptom rather than the cause. Before installing another PIM, check the DC source, polarity, field wiring, connector condition, and downstream power-supply health.
  6. Do not assume a second supply is electrically identical to the first.
    In a redundant configuration, Bently Nevada allows different source types to be used for the primary and backup positions. Confirm the actual rack configuration before modifying either supply position.

 

Related Products

  • Bently Nevada 3500/15 114M5330-01 — Low Voltage DC Power Supply Module. This is the direct companion to 114M5335-01. The 114M5335-01 provides the DC input interface; 114M5330-01 converts the incoming DC power into the voltages required by the 3500 rack.
  • Bently Nevada 3500/15 114M5329-01 — High Voltage DC Power Supply Module. Designed for 88–140 VDC input applications. It belongs to the same 3500/15 family but is not appropriate for a 20–30 VDC source.
  • Bently Nevada 3500/15 115M7750-01 — High Voltage DC Power Input Module. This is the associated PIM for the high-voltage DC supply arrangement and should not be substituted for the 114M5335-01 on a 24 VDC installation.
  • Bently Nevada 3500/15 106M1079-01 — Universal AC Power Supply Module. Used with the universal AC PIM for 85–264 VAC RMS input. It is an alternative power-source architecture rather than a direct replacement for the low-voltage DC assembly.
  • Bently Nevada 3500/15 106M1081-01 — Universal AC Power Input Module. Used with the universal AC power-supply module. It is relevant when a 3500 rack is being configured for AC rather than 20–30 VDC input.
  • Bently Nevada 3500/15 133292-01 — Legacy Low Voltage DC Power Supply Module. This belongs to the earlier 3500 power-supply generation. Do not substitute it for a current-generation 114M5330-01 without verifying the complete rack and PIM compatibility.
  • Bently Nevada 3500/15 133300-01 — Legacy Low Voltage DC Power Input Module. It is the legacy counterpart to the current low-voltage DC PIM family. Existing legacy racks need to be identified before selecting between these assemblies.
  • Bently Nevada 3500/15 01720045 — Replacement fuse for the low-voltage DC PIM and legacy low-voltage DC power-input module. Useful when diagnosing a blown PIM fuse before replacing the entire assembly.
  • Bently Nevada 3500 Rack — The chassis that houses the 3500/15 power-supply assembly and the machinery-monitoring modules. The 3500/15 occupies the designated power-supply position on the left side of the rack.

Procurement note: The 114M5335-01 is specifically the Low Voltage DC Power Input Module (PIM), not the complete 3500/15 power supply. For a replacement order, verify the installed PIM part number, the associated 114M5330-01 power-supply module, the actual DC input voltage, legacy/current hardware generation, and whether the rack uses single or redundant supplies. Bently Nevada’s current datasheet should be treated as the final compatibility reference before installation.
