Description
Bently 3500 33
Technical Specifications
- Model Number: 3500/33
- Channel Count: 16 independent relay channels
- Relay Type: Single-Pole, Double-Throw (SPDT)
- System Compatibility: Bently Nevada 3500 Framework
Key Features
- High-Density Output: Consolidates 16 relay channels into one module, optimizing framework slot utilization.
- Comprehensive Logic Support: Each of the 16 relays can be independently programmed with AND/OR logic using any combination of rack alarms.
- Software Switches: Supports temporary bypassing or inhibiting of specific relay channels via software for safe maintenance operations.
Application Scenarios
Ideal for large, multi-stage turbomachinery (such as steam turbines and centrifugal compressors) requiring numerous discrete alarm and trip signals for various bearings, seals, and auxiliary systems.
Performance Parameters
- Contact Rating: 3A @ 240 VAC / 30 VDC
- Arc Suppressors: 250 Vrms installed as standard to protect contacts
Material Composition
Heavy-duty industrial enclosure with epoxy-sealed relays to prevent arc tracking and ensure long-term reliability in high-vibration environments.
Structural Characteristics
Full-height module featuring a dense array of 16 front-panel status LEDs. Requires precise alignment during insertion due to the high pin-count backplane connector.
Working Principle
Operates identically to the 3500/32 but with an expanded internal microprocessor capable of evaluating 16 independent logic matrices simultaneously, driving a larger number of external physical contacts.
Installation Requirements
Due to the high number of external connections, meticulous wire routing and strain relief are mandatory to prevent terminal damage. Install in any slot to the right of the TDI module.
Usage Precautions
Carefully map the 16-channel logic in the configuration software to prevent cross-wiring errors. Regularly inspect the terminal block for tightness, as vibration can loosen connections over time.
