Introduction
The 3500/05-02-04-00-00 is a specific configuration of a Relay Module for the Bently Nevada 3500 Machinery Protection System.
This module is a critical output device within the 3500 system, providing the physical interface to initiate actions in the outside world based on the system's monitoring logic. It houses electromechanical or solid-state relays that are activated when other monitoring modules (like vibration or speed monitors) trigger an alarm or danger condition. Its primary function is to convert the system's internal alarm signals into real-world actions, such as shutting down a machine (trip), activating an alert beacon, or signaling the plant's Distributed Control System (DCS).

Application Scenarios
The 3500/05 Relay Module is the primary "action" module in the protection system, used wherever a automated physical response is required based on machine condition.
Critical Machine Shutdown (Trip):
Turbines, Compressors, Pumps: The most critical application. When a vibration, speed, or temperature monitor detects a dangerous condition, it commands the relay module to de-energize, which breaks the circuit to the machine's shutdown solenoid, initiating an immediate and safe shutdown to prevent catastrophic failure.
Alarm Annunciation:
Control Room Alerts: Used to activate warning lights, audible alarms, or annunciator panels in the control room when a monitor reaches an Alert (warning) condition, notifying operators of a developing problem that requires attention.
Auxiliary System Control:
Sequencing and Logic: Can be used to control auxiliary systems based on machine state. For example, it can be programmed to start lube oil auxiliary pumps if bearing temperature rises or to open a bypass valve upon a specific process condition.
Interface with Plant Control Systems (DCS/PLC):
Hardwired Safety Interface: Provides a robust, hardwired safety interface to the plant's main control system. The relay's dry contact output is a universal and highly reliable signal that can be wired directly into a DCS or PLC digital input module to communicate the machine's protection status.
