Product Introduction
The Bently Nevada 3500/32-01-00 is a high-reliability 4-Channel Relay Module, purpose-built to deliver alarm and shutdown logic in the 3500 Series Machinery Protection System. Acting as a critical interface between the monitoring system and external equipment, the module provides user-configurable relays that respond to system alarms, operating conditions, or user-defined logic.
Each relay channel is completely independent and software-configurable through the 3500 System Configuration Software. This module is essential for integrating machine protection functions with broader plant control systems such as Distributed Control Systems (DCS), Programmable Logic Controllers (PLC), or Safety Instrumented Systems (SIS).
