Overview
The Bentley Nevada 3300/03-02-01 is a Serial Data Interface (SDI) equipped System Monitor module for the Bentley Nevada 3300 Series machinery monitoring system. Installed in the second position of the 3300 monitoring rack, this unit centralizes system management, communications, and logic functions while maintaining full isolation from the critical machinery protection path. The 3300/03-02-01 configuration adds bi-directional serial data communications capability, allowing real-time integration with plant DCS, historian, and asset management systems.
Key Features
- Serial Data Interface (SDI) enables bi-directional communication with external monitoring and SCADA systems
- Continuous voltage monitoring of system power supplies with front-panel LED status indication
- Isolated relay logic architecture—system functions independent from machine protection operations
- Compatible with buffered transducers and direct-output proximity sensors used in 3300 monitoring configurations
- Modular design supports upgrades from basic 3300/01 monitor or cross-compatibility with DDI (Dynamic Data Interface) options
- Thermal stability across industrial temperature ranges suitable for power generation, petrochemical, and rotating machinery applications
