The Bently Nevada 3500/33-01-R0, also cataloged as the 3500/33 16-Channel Relay Module, operates as a dedicated hardware component for relay output execution and voting logic control within 3500 Machinery Condition Monitoring systems.

Suffix Breakdown & Model Matrix

• 3500/33: Base model designation for the 16-channel relay output module.
• 01: Output module option specifying the 16-channel standard relay output configuration with silver contacts.
• R0: Factory revision and mounting identifier associated with standard system builds.

Hardware Specifications

Machinery Protection & Rotor Dynamics

• Alarm Drive Logic Execution: Processes individual measured variables, alert statuses, danger statuses, and Not-OK conditions through programmable AND and OR Boolean voting logic configured via the 3500 Rack Configuration Software.
• Eddy-Current Probe Scaling & Cross-Talk Suppression: Interfaces directly with monitor modules tracking rotor dynamics, ensuring that overall vibration amplitudes, gap voltage thresholds, and filtered phase parameters trigger corresponding relay states without signal degradation.
• Fail-Safe and Operation Modes: Features switch-selectable options for Normally De-energized (ND) or Normally Energized (NE) operation across four groups of four channels to maintain strict trip logic integrity.

Ordering Info

• 1 x 3500/33 Main Relay Module (Part Number 162096-01)
• 1 x 16-Channel Relay I/O Module with Terminal Headers
• 1 x 16-Channel Relay Module User Guide (Document 162291)
• 1 x Grounding Wrist Strap (Single Use)

Field Installation Guidelines

• Rack Slot Allocation: Install the main module in any available front slot to the right of the Transient Data Interface (TDI) module, placing the associated I/O module in the corresponding rear slot.
• Terminal Wiring: Secure field wiring to the 16-position green connector headers, ensuring that applied voltages do not exceed specified limits to prevent insulation breakdown or high-voltage shock hazards.
• Configuration Verification: Verify that the rack runs 3500 Rack Configuration Software version 3.3 or later, Data Acquisition Software version 2.40 or later, and Data Display Software version 1.40 or later prior to system startup.

Frequently Asked Questions

• What is the minimum switched load requirement for the standard relay contacts?

  The standard silver contacts require a minimum switched load of 100 mA at 5 Vdc.

• Can the 3500/33 module be placed in any rack slot?

  The module can occupy any available monitor or relay slot located to the right of the TDI module, but cannot use slots reserved exclusively for power supplies and the TDI.

• How are relay operation modes selected on the module?

  Relay operation is configured by four groups of four channels using hardware selection switches for Normally Energized or Normally De-energized operation.

• What software version is required to configure the 3500/33 module?

  Configuration requires 3500 Rack Configuration Software version 3.3 or later.

• Are the relay contacts epoxy-sealed?

  The relays feature epoxy-sealed environmental sealing and include factory-installed 250 Vrms arc suppressors.

• What is the power consumption of the module during normal operation?

  The typical power consumption is 5.8 watts.

• Does the module support hot-swapping?

  Modules within the 3500 rack are designed to be inserted or removed from the rack backplane while rack power is applied, provided hazardous live terminals are isolated.

• What type of relay output configuration does option 01 provide?

  Option 01 provides a 16-channel standard relay output using single-pole double-throw (SPDT) contacts with silver material.
