The 3300/53-03-02-00-60-05-00-00-00 is a high-integrity Overspeed Detection Module within the Bently Nevada 3300 Machinery Protection System.
This module continuously monitors rotational speed inputs from proximity probes or magnetic pickups installed on critical rotating equipment such as steam turbines, gas turbines, and large centrifugal compressors. It functions as an independent safety layer, providing autonomous overspeed protection even if communication with the primary DCS is lost.
Designed for rapid response, the 3300/53 can initiate emergency trip signals within milliseconds once a configured speed threshold is exceeded. Its hardware-centric architecture ensures reliable operation in high-vibration, high-energy industrial environments.
Multi-channel input and voting logic capabilities (e.g., 2-out-of-3 configuration) significantly enhance system safety by minimizing nuisance trips while maintaining overspeed protection integrity.

The 3300/53-03-02-00-60-05-00-00-00 is widely deployed in:
Steam turbine overspeed protection systems
Gas turbine generator sets
Large centrifugal compressors
Hydroelectric turbine-generator units
High-inertia industrial fans and pumps
It is considered an industry-standard safety module for protecting high-value rotating assets from catastrophic mechanical failure caused by overspeed events.
How does the voting logic improve safety?
The module supports configurable voting schemes such as 2-out-of-3 (2oo3) logic. In this configuration, at least two independent speed channels must detect an overspeed condition before the trip relay is activated. This reduces false trips caused by a single sensor fault while maintaining protection integrity.
Can speed setpoints be adjusted during operation?
Although monitoring remains active continuously, setpoint adjustments and self-tests are typically performed via the 3300 rack interface or configuration tool during scheduled maintenance to prevent unintended trip activation.
