Overview Manuals Core Applications Ordering Considerations

Features:

  • Spare 16-Channel Relay Control Module
  • 3500/33 16-Channel Relay Module
  • Full-height module that provides 16 relay outputs
The Bently Nevada 3500/33 16-Channel Relay Module is a full-height module that provides 16 relay outputs. You can place any number of 16-channel relay modules in any of the slots to the right of the Transient Data Interface (TDI) Module.

Each output of the 3500/33 16-Channel Relay Module can be independently programmed to perform voting logic. Each relay of the module includes Alarm Drive Logic.

The 3500/33 149986-01 Bently Nevada 16-Channel Relay Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Programming for the Alarm Drive Logic uses AND and OR logic and may use the following:
  • Alarming inputs (alert and danger statuses)
  • Not-OK
  • Individual Measured Variables from any monitor channel or any combination of monitor channels in the rack
You can program the Alarm Drive using the 3500 Rack Configuration Software.
1.The 3500/33 16-Channel Relay Module requires the 3500 Rack Config, version 3.3 or later.
2.The 3500/33 requires the 3500 Data Acquisition Software, version 2.40 or later.
3.The 3500/33 16-Channel Relay Module requires the 3500 Data Display Software, version 1.40 or later.
4.When ordered with the multiple approvals option (-02), the 3500 monitor is certified to Zone 2 standards, including ATEX and North American zones.
5.The North American Division 2 standards associated with the CSA-only approvals option (-01) have been de-rated to 30 Vrms to comply with 61010-1 type test requirements.

Technical notes

As the core high-density logic output gateway of the 3500 mechanical protection system, this module is a full-height 16-channel programmable control motherboard. It is specifically responsible for receiving violation statuses from each monitoring channel from the rack backplane, performing complex matrix voting locally through its integrated advanced alarm drive logic, and driving the physical closure of downstream relays, thereby outputting precise, high real-time mechanical protection interlock cut-off signals to downstream DCS, SIS, or Emergency Stop (ESD) systems.

Ask our team:

  • What operational role does the 3500/33 149986-01 fulfill within a 3500 Machinery Protection System?
    The 3500/33 149986-01 functions as a high-capacity 16-channel relay output module, providing robust interface logic between monitored conditions and external plant control systems. It translates discrete trip and alarm signals from vibration, speed, or process sensors into reliable, isolated relay outputs for automated protective actions.
  • How does the internal circuitry of 3500/33 149986-01 ensure signal integrity and isolation across all 16 channels?
    The 3500/33 149986-01 incorporates opto-isolated driver circuits and fail-safe relay contacts that prevent cross-talk between channels while maintaining precise response times. This architecture ensures that each channel independently transmits alarm or trip conditions without interference or signal degradation.
  • Why is 3500/33 149986-01 critical for integrating machinery protection signals with plant-wide control and shutdown systems?
    By providing isolated, high-current relay outputs for multiple monitored points, the 3500/33 149986-01 enables seamless interface with programmable logic controllers (PLCs), distributed control systems (DCS), and emergency shutdown circuits, ensuring that machinery protection actions are executed reliably in critical conditions.
  • In what environmental conditions is 3500/33 149986-01 validated to operate reliably?
    The 3500/33 149986-01 is rated for industrial environments with elevated ambient temperatures, vibration, humidity, and electromagnetic interference, ensuring stable operation even in harsh turbine, compressor, or pump installations, as specified in the datasheet.
  • What specifications of the relay contacts in 3500/33 149986-01 enhance protective reliability and compatibility with external circuits?
    The 3500/33 149986-01 utilizes mechanical relays rated for both AC and DC loads with defined voltage and current limits per channel. The contacts are designed for low bounce, high endurance, and fail-safe behavior, enabling reliable actuation of alarms, shutdown valves, and interlock systems.
  • Why is precise channel mapping essential when configuring 3500/33 149986-01 for complex machinery monitoring?
    The 3500/33 149986-01 requires accurate assignment of monitored points to relay outputs to ensure that alarms and trips correspond correctly to the intended machinery parameters. Misconfiguration can lead to delayed or unintended actuation, reducing protective effectiveness.
