Bently Nevada 3500/33-01-00 Technical Specifications, Product Introduction, Applications, Advantages, Brand, Series, and Recommended Models
Product Introduction
The Bently Nevada 3500/33-01-00 is a high-density 16-Channel Relay Module designed for use within the 3500 Machinery Protection System. It provides an expanded relay output interface between the machinery monitoring system and external plant control, alarm, and protection circuits.
The primary function of the 3500/33-01-00 is to convert monitoring conditions generated by modules installed inside the 3500 rack into reliable physical relay outputs. These outputs allow external devices to receive alarm signals, shutdown commands, equipment status information, and control signals.
Compared with lower-channel relay modules, the 16-channel design provides a larger number of relay outputs within a single module, making it suitable for complex machinery protection systems requiring multiple alarm and trip functions.
The module allows each relay channel to be independently configured according to different machinery protection requirements. Users can assign relay outputs to different monitoring conditions, including vibration alarms, temperature warnings, shaft position changes, overspeed conditions, and other protective events.
The 3500/33-01-00 is designed for applications where a large number of hardwired relay outputs are required. By integrating multiple relay functions into one rack module, it reduces cabinet space requirements, simplifies wiring, and improves overall system organization.
The module communicates through the internal 3500 rack backplane, allowing fast and reliable transfer of protection signals between monitoring modules and relay outputs.
With its modular construction, industrial-grade components, and flexible configuration capability, the 3500/33-01-00 provides a dependable solution for protecting critical rotating machinery in demanding industrial environments.

Product Features
The 3500/33-01-00 is designed to provide a high-capacity relay interface for machinery protection systems that require multiple external output signals.
The module provides sixteen independent relay channels, allowing a large number of alarm and shutdown functions to be handled from one compact rack position.
Each relay can be individually configured according to specific machinery protection requirements. This allows users to create customized protection logic for different types of rotating equipment.
The module supports flexible relay assignment, enabling output signals to be generated from various monitoring parameters such as vibration levels, temperature conditions, shaft position measurements, speed abnormalities, and system status information.
The internal rack communication design ensures fast signal transmission and reduces the amount of external wiring required between monitoring equipment and control systems.
Front-panel LED indicators provide clear status information, allowing operators and maintenance personnel to quickly determine module operating conditions.
The industrial relay construction provides reliable switching performance for applications requiring continuous operation and fast response.
The modular plug-in design allows easy installation, replacement, and maintenance without requiring major system modifications.
The compact rack-mounted structure helps optimize control cabinet space while providing a large number of relay outputs.
Product Advantages
The biggest advantage of the 3500/33-01-00 is its high relay output capacity. Sixteen independent relay channels allow complex machinery protection systems to be designed with fewer additional interface devices.
The high-density design reduces cabinet space requirements and simplifies system architecture compared with using multiple individual relay modules.
The module provides excellent flexibility because each relay output can be configured independently according to different protection requirements.
The programmable relay logic allows the same hardware platform to support various industrial applications, reducing the need for hardware replacement when system requirements change.
The module improves machinery protection reliability by providing direct and dependable alarm and shutdown outputs when abnormal operating conditions occur.
Its strong compatibility with the 3500 platform allows easy integration with existing monitoring systems.
The module provides reliable operation in industrial environments where vibration, electrical noise, and continuous operation are common.
The modular design simplifies maintenance procedures and reduces downtime by allowing quick replacement when required.
The combination of high channel density, flexible configuration, and reliable performance makes the module suitable for large-scale machinery protection applications.
