More Information

Overview Manuals Relay Role Alarm Wiring Spare Selection Product Applications

Features:

  • Spare-module identity: 81546-01 is listed as the dual-hermetic relay module for the 3300/45 monitor.
  • Alarm contacts: The documented installation provides Alert and Danger relay contact sets.
  • Configurable operation: Plug-in jumpers support normally energized or de-energized relay modes.
For a 3300/45 spare request, 81546-01 identifies the relay module rather than the full differential-expansion monitor.

The monitor's rear wiring diagram shows NC, ARM and NO connections for the Alert and Danger circuits, giving maintenance teams a concrete way to compare the installed alarm wiring.

The existing monitor and jumper arrangement are useful matching details when arranging a replacement module for the rack.

Apter Power can support an 81546-01 Bently Nevada Dual Hermetic Relay Module enquiry with a scoped quotation and relevant 3300/45 technical documentation.
Bently Nevada 81546-01 Dual Hermetic Relay Module Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Listed spare: 81546-01 is the dual-hermetic relay module in the 3300/45 spare-parts list.
  • Monitor relationship: The module belongs behind a 3300/45 monitor; it is not the complete monitor.
  • Alarm function: The documented arrangement uses separate Alert and Danger relay contacts.
  • Option distinction: The 3300/45 ordering table distinguishes the hermetic relay option from epoxy, no-relay and quad-relay versions.
  • Contact sets: The 3300/45 diagram shows NC, ARM and NO terminals for Alert and Danger.
  • Relay mode: Plug-in jumper choices include normally energized and normally de-energized alarm relays.
  • Voting choice: The document lists OR and AND danger-relay voting options for the monitor arrangement.
  • System boundary: Alarm setpoints and recorder outputs are monitor functions, not independent specifications of 81546-01.
  • Dual hermetic: 81546-01 is the listed spare when dual hermetically sealed relays are required.
  • No-relay contrast: 81544-01 is the separate no-relay spare and does not offer the same alarm contacts.
  • Epoxy contrast: 81545-01 is the distinct dual-epoxy spare rather than the hermetic option.
  • Quad contrast: 84152-01 is the separate quad-relay spare; it is not an alias for 81546-01.
  • Differential expansion: In a 3300/45 installation, the monitor follows rotor-to-casing axial displacement.
  • Startup supervision: The documented measurement is relevant to thermal expansion during startup and shutdown.
  • Alert output: The module provides the relay path for the configured Alert alarm circuit.
  • Danger output: The second contact set supports the configured Danger alarm circuit.
Description
81546-01 is the dual-hermetic spare relay module listed for Bently Nevada's 3300/45 differential-expansion monitor. It provides the alarm-relay option rather than an independent measurement or display function.

The 81546-01 module is selected where hermetically sealed Alert and Danger relay contacts are required. The 3300/45 wiring diagram shows normally closed, arm and normally open terminals for each relay, so the installed alarm circuit determines the contact wiring.

For an 81546-01 spare request, the parent monitor and relay arrangement are the useful matching details. Apter Power can help quote the module and provide the relevant 3300/45 technical document without treating whole-monitor ratings as card specifications.
Alternative Names
Bently Nevada 81546-01 BN 81546-01 81546 01 8154601 81546-01 dual hermetic relay module 3300/45 81546-01 Bently Nevada 81546 01 BN 81546 01
Technical notes
The 81546-01 relay module carries the 3300/45 Alert and Danger output contacts; measurement input and power belong to the host monitor, not this spare card. Relay mode and NC/ARM/NO wiring determine how the external alarm circuit responds to a state change. Apter Power can help compare the existing relay option before quotation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can 81546-01 replace an entire 3300/45 monitor?
This number identifies the dual-hermetic relay spare, not a complete monitor. Apter Power can help quote the appropriate spare after the installed monitor and relay option are identified.
Will 81546-01 suit every 3300/45 relay configuration?
The 3300/45 ordering information distinguishes dual-hermetic, epoxy, no-relay and quad-relay options. Matching the installed option matters before choosing this spare card.
Why might alarm behavior change after fitting 81546-01?
The documented Alert and Danger outputs can be arranged for normally energized or de-energized operation. The installed jumper and NC/ARM/NO wiring determine the external circuit response; our team can help compare the configuration.
Can 81546-01 take a transducer input directly?
This is the relay module; the 3300/45 monitor handles measurement inputs. For a repair, the quote should distinguish the alarm-output spare from the monitor electronics.
