Bently Nevada 3500/33-01-01 Technical Specifications, Product Introduction, Applications, Advantages, Brand, Series, and Recommended Models
Product Introduction
The Bently Nevada 3500/33-01-01 is a high-capacity 16-Channel Relay Module designed for use within the 3500 Machinery Protection System. It provides a reliable and flexible interface between the machinery monitoring system and external plant equipment, including alarm systems, control systems, protective shutdown circuits, and equipment interlocking devices.
The main purpose of the 3500/33-01-01 is to convert internal monitoring conditions from the 3500 system into physical relay outputs. When abnormal machinery conditions are detected, the module can activate external circuits according to configured protection logic.
The module provides sixteen independent relay channels, allowing multiple alarm and shutdown functions to be managed from a single rack position. This high-density relay design is particularly useful for complex machinery protection systems that require numerous output signals.
Each relay channel can be configured independently according to different operational requirements. Users can assign relay outputs to specific monitoring events, including excessive vibration, high temperature, abnormal shaft position, overspeed conditions, and other machine protection parameters.
The 3500/33-01-01 is designed to improve system flexibility while reducing installation complexity. By integrating many relay functions into one compact module, it reduces the requirement for additional external relay devices and helps optimize control cabinet space.
The module communicates through the internal rack backplane, allowing fast and stable signal transmission between monitoring modules and relay outputs. This integrated architecture improves system reliability and reduces external wiring requirements.
Built for continuous industrial operation, the module provides dependable performance in environments where vibration, electrical interference, temperature variations, and long operating cycles are common.
The module is widely used for protecting critical rotating equipment such as turbines, compressors, generators, pumps, motors, and other industrial machinery where reliable alarm and shutdown response is essential.

Product Features
The 3500/33-01-01 is designed to provide a large number of relay outputs within a compact rack-mounted module. It is suitable for applications where multiple protection actions need to be controlled simultaneously.
The sixteen independent relay channels allow users to manage a wide range of machinery protection functions from one module. Each channel can operate independently and can be assigned to different alarm or shutdown conditions.
The module supports flexible relay configuration, allowing engineers to customize protection logic according to individual machine requirements.
The relay outputs can be used for different functions, including:
- High vibration alarms
- Shutdown commands
- Equipment status indication
- Process control signals
- Safety interlocks
- External annunciation
The module receives information from monitoring modules installed in the 3500 rack and converts these signals into reliable electrical relay outputs.
The internal rack communication design improves response speed and reduces the amount of external wiring required between monitoring equipment and plant control systems.
Front-panel LED indicators provide convenient visual monitoring of module operation and relay status. This helps maintenance personnel quickly identify system conditions during inspection and troubleshooting.
The industrial-grade relay design provides stable switching performance for long-term operation in demanding environments.
The modular plug-in structure allows simple installation and replacement, reducing maintenance time and minimizing equipment downtime.
Product Advantages
