📘 BENTLY 3500/33 149986-01 Dual Redundant Relay Module
The BENTLY 3500/33 149986-01 is a dual redundant relay module designed for high-reliability alarm and trip functions within the Bently Nevada 3500 Machinery Protection System. Built for critical industrial environments, this module provides secure relay outputs for interfacing machinery monitoring signals with plant control systems. Its dual-redundant architecture ensures continuous operation, even if a single relay path fails, making it ideal for mission-critical applications such as power generation, oil & gas, and petrochemical processes.
⚙️ Product Overview
The 3500/33 module acts as the interface between monitored machine conditions and external shutdown, alarm, or annunciator systems. By offering dual-redundant relay contacts, it ensures that alarm and trip events are transmitted reliably. The module is compatible with all standard 3500 rack configurations and supports hot-swappable replacement for minimal downtime. Its diagnostic capabilities allow maintenance personnel to quickly identify relay or module issues without halting operations.
