Description

Configured for relay output control and alarm logic execution in the 3500 Machinery Protection System, the Bently Nevada 3500/34 (3500/34 4-Channel Relay Module) provides direct physical/electrical execution.

Hardware Specifications

Rotor Dynamics and Relay Signal Interface

The Bently Nevada 3500/34 provides four programmable relay outputs for machinery protection logic execution within the 3500 monitoring system. The module receives configured alarm conditions from the monitoring rack and transfers relay signals for external alarm, shutdown, and control circuits.

The relay module supports independent alarm logic configuration and voting functions. These functions allow relay states to follow defined monitoring conditions for machinery protection operations.

The 3500/34 interfaces monitoring decisions with external electrical circuits through controlled relay outputs. The module maintains defined signal behavior for alarm annunciation, protective shutdown interfaces, and equipment control applications.

Frequently Asked Questions

Q: What is the relay channel capacity of the 3500/34 module?
A: The module provides four programmable relay output channels for alarm, shutdown, and control functions within the 3500 Machinery Protection System.

Q: Does the 3500/34 support independent relay logic configuration?
A: Yes. The module supports independent alarm logic configuration and relay voting functions.

Q: What installation method does the 3500/34 require?
A: The module installs in a 3500 Rack full-height front slot and requires connection with the corresponding rear I/O module.

Field Installation Guidelines

Install the 3500/34 module into the designated full-height front slot of the 3500 rack. Verify proper mechanical alignment with the rear I/O module before securing the module assembly.

Route relay output wiring separately from high-voltage power conductors to reduce electromagnetic interference. Apply appropriate cable shielding and grounding practices according to site electrical standards.

Verify relay terminal connections, rack power conditions, and configured alarm logic before placing connected machinery protection circuits into operation.

Before removing or replacing the module, confirm the required maintenance condition for connected protection functions and verify that external relay circuits remain controlled during service procedures.
