Description
Bently Nevada 3500/33-01-00 16-Channel Relay Module Technical Overview
1. Product Details
- Core Composition: A full-height 16-channel relay module for the Bently Nevada 3500 Machinery Protection System, assembled from the main control board 149986-01 and the matching I/O termination board 149992-01.
- Physical & Electrical Specs: Typical power consumption 5.8W, relay contact type is Single Pole Double Throw (SPDT), with standard 250 Vrms arc suppressor pre-installed, relay contact life reaches 10,000 operating cycles.
- Installation Rule: Can be placed in any slot on the right side of the Transient Data Interface (TDI) Module within the 3500 rack system, supporting multiple modules stacked for channel expansion.
2. Primary Applications
- Critical Machinery Protection: Deployed on turbines, compressors, pumps and other key rotating equipment to control alarm and interlock trip signals.
- Industrial Scenarios: Widely used in petrochemical, power generation, metallurgy and other heavy industries, integrated into DCS, PLC or annunciator systems for critical process safety control.
- System Compatibility: Fully compatible with all 3500 series monitoring units, supporting custom alarm logic configuration via the 3500 Rack Configuration Software.

3. Series Model Variants
- Standard Configurations: 3500/33-01-00, 3500/33-01-00-CN, 3500/33-02-00, 3500/33-03-00, 3500/33-04-00.
- I/O Terminal Options: Non-isolated internal terminals, isolated external terminals, intrinsically safe barrier terminals for different field wiring and hazardous area requirements.
- Channel Expansion Options: 16 independent relay outputs per module, allowing multiple modules to be installed in one rack to expand the total number of interlock points.
4. Core Features
- Independent Programmability: Each of the 16 relay outputs can be individually configured to execute custom voting logic via the 3500 rack configuration software.
- Built-in Alarm Drive Logic: Integrated AND/OR logic programming for alarm and danger status signals from any monitoring channel or channel combination in the rack.
- Real-Time Status Indication: Equipped with front-panel OK LED indicator, which illuminates steadily when the module is operating normally, providing intuitive visual health feedback for on-site personnel.
5. Main Functions
- Alarm Signal Output: Activates corresponding relays based on system preset alarm conditions, sending status signals to external DCS, PLC or annunciator systems.
- Interlock Trip Control: Executes customized protection logic to trigger equipment shutdown when abnormal parameters exceed safety thresholds, preventing costly mechanical damage.
- Status Feedback: Transmits real-time relay working status back to the 3500 system and linked System 1 condition monitoring platform for proactive maintenance management.
