The Bently Nevada 3500/33-01-02 is a high-density 16-Channel Relay Module designed for use in the 3500 Machinery Protection System. It provides a flexible and reliable interface between machinery monitoring modules and external equipment such as alarm systems, shutdown circuits, process control systems, and safety interlock devices.
The main function of the 3500/33-01-02 is to convert protection signals generated by the monitoring modules inside the 3500 rack into physical relay outputs. When a monitored machine parameter exceeds a configured limit, the relay module can activate external circuits to provide warning, control, or shutdown actions.
Compared with standard low-channel relay modules, the 16-channel design provides a greater number of output points within a single rack position. This makes the module especially suitable for complex machinery protection systems where many independent alarm and trip signals are required.
The module contains sixteen independent relay channels, allowing each relay to be configured according to specific machinery operating requirements. Different relay channels can be assigned to different protection conditions, such as vibration alarms, temperature warnings, overspeed events, shaft position changes, or equipment status indications.
The 3500/33-01-02 is designed to simplify system architecture by reducing the number of external relay devices required in a protection cabinet. Its compact rack-mounted design helps save installation space while maintaining a high level of functionality.
The module communicates through the internal rack backplane, providing fast and stable data transfer between monitoring modules and relay outputs. This integrated design reduces wiring complexity and improves overall system reliability.
The product is suitable for continuous operation in demanding industrial environments. Its reliable relay switching capability, flexible configuration, and modular design make it an important component for protecting critical rotating machinery.
