The Bently Nevada 3500/33 149986-01 is a 16-Channel Relay Module, an essential component of the 3500 Machinery Protection System. This full-height module provides 16 relay outputs which can be independently programmed to perform voting logic based on inputs from monitor channels within the rack. It is designed to provide reliable and configurable machinery protection by activating alarms or initiating automatic shutdowns when monitored parameters exceed user-defined setpoints. The module’s primary function is to translate the system’s monitoring status into physical relay actions for external annunciators, control systems, or emergency shutdown (ESD) systems, ensuring plant safety and operational integrity.
