Product Details
The 3500/33 149992-03 is a full-height, 16-channel relay output module designed for the Bently Nevada 3500 Machinery Protection System. It provides configurable relay outputs to interface with external machinery alarm systems, annunciators, or control logic based on predefined rack alarm conditions. This specific model features sixteen independent relay channels driven by voting logic configurations to manage critical trip or warning outputs reliably.
Module Architecture and Channel Configuration
The module occupies a single full-height slot within the 3500 rack and communicates directly with the rack's rack interface module and adjacent monitor modules via the system backplane. It contains sixteen relay channels, where each channel can be independently programmed using the 3500 Configuration Software. The software allows engineers to map individual channels to specific alarm conditions, such as Danger, Alert, or Fault statuses from any monitor module present in the rack.
Output Logic and Voting Options
Each relay on the module can be configured as normally energized or normally de-energized to suit fail-safe system design requirements. The module supports sophisticated AND/OR voting logic combinations, enabling operators to combine multiple alarm criteria before a relay state changes. This flexibility prevents single-sensor spurious trips while ensuring immediate mechanical shutdown when true multi-parameter machinery degradation occurs.
