Key Features and Advantages

Flexible Alarm Drive Logic: Each relay channel features programmable “Alarm Drive Logic” using AND and OR gates. This allows engineers to create complex voting logic utilizing alert and danger inputs from any monitor channel or combination of channels within the rack.
Independent Channel Control: All four relay outputs can be independently programmed to meet specific application requirements, providing granular control over machinery protection strategies.
High Reliability & Industrial Grade Design: Built with industrial-grade materials and solid-state switching technology, the module offers high load capacity, excellent anti-interference capabilities, and long-term stability in harsh industrial environments.
Seamless System Integration: Fully compatible with the Bently Nevada 3500 series ecosystem. It integrates effortlessly with other monitor modules and the 3500 Rack Configuration Software for comprehensive system management.
Enhanced Diagnostics: The module supports advanced diagnostic and monitoring functions, allowing for real-time status detection and rapid troubleshooting to minimize system downtime.

Application Areas

The 3500/32 module is widely deployed in industries requiring continuous, online monitoring and protection for large-scale rotating and reciprocating machinery. Key applications include:

Power Generation: Steam turbines, gas turbines, and generators.
Oil & Gas: Centrifugal and reciprocating compressors, pumps, and turbo-expanders.
Petrochemical & Chemical: Critical process compressors, fans, blowers, and gearboxes.
Heavy Industry: Motors, exciters, extruders, and pelletizers.

Installation and Maintenance

Installation: The 3500/32 is a hot-swappable module. It can be installed or replaced without powering down the rack, significantly reducing maintenance downtime. Simply slide the module into any available full-height slot to the right of the RIM and secure it with the front panel screws.
Configuration: Use the 3500 Rack Configuration Software to define the alarm drive logic, set relay states (normally energized/de-energized), and assign specific monitor channel inputs to each relay output.
Maintenance: The module is designed for minimal maintenance. Regular visual inspection of the front panel LEDs (OK, Active) is recommended to verify operational status. If a fault is indicated, the module can be quickly replaced in the field. Always ensure proper grounding and verify relay contact ratings before connecting external loads.
