Description

Designed for continuous machinery protection, the Bently Nevada 3500/61-01-00 processes temperature inputs from resistance temperature detectors (RTDs) and thermocouples (TCs). This six-channel module continuously compares these temperature inputs against user-defined alarm setpoints to protect critical industrial machinery from thermal damage. The 3500/61-01-00 variant is configured with non-isolated RTD/TC I/O modules utilizing internal terminations, providing clean, direct wiring connections within the rack enclosure.

In addition to active alarm monitoring, this module provides dedicated analog recorder outputs for each of its six channels. These recorder outputs provide proportional continuous signals to external control systems, such as Distributed Control Systems (DCS), Programmable Logic Controllers (PLCs), or strip chart recorders, ensuring seamless historical data logging and process visualization.

Features

  • Continuous monitoring of up to six independent temperature channels.
  • Compatible with both thermocouple and RTD thermal sensors.
  • Provides independent analog recorder outputs for each channel to interface with external systems.
  • Utilizes an internal termination I/O module configuration for direct-to-board field wiring.
  • Supports customizable alarm configurations, including Alert and Danger setpoints, with programmable time delays.
  • Fully integrates with the Bently Nevada 3500 Machinery Protection System rack, backplane, and software.

Applications

  • Steam, gas, and hydro turbine bearing temperature tracking.
  • Large electric motor and generator winding and stator protection.
  • Compressor and industrial pump housing temperature monitoring.
  • Industrial gearboxes, machinery enclosures, and lube oil reservoir monitoring.

Installation Guidelines

  • Ensure the 3500 rack system is completely powered down before inserting or removing the I/O module or monitor mainboard.
  • Secure the internal termination blocks properly using the module's retention screws to guarantee reliable physical and electrical contact with the backplane.
  • Use shielded, twisted-pair cabling for all sensor runs to minimize electromagnetic interference (EMI) and radio frequency interference (RFI).
  • Ensure shielding is grounded according to plant and system standard schematics, typically at the monitor rack common ground only.

FAQ

What is the primary function of the Bently Nevada 3500/61-01-00 module?

The 3500/61-01-00 is a 6-channel temperature monitor that processes inputs from RTDs and thermocouples, provides active machinery protection through alarm setpoints, and features dedicated analog outputs for external recording or control systems.

What does the -01 I/O module option represent?

The -01 option designates a non-isolated RTD/TC I/O module configuration featuring internal terminations, allowing field wiring to connect directly to terminals mounted on the I/O module.

Does this model carry hazardous area approvals?

The -00 agency approval option on this specific module (3500/61-01-00) signifies that it does not come with standard hazardous area agency approvals.

How many sensor inputs can be connected to the 3500/61-01-00?

This module can accommodate up to six independent temperature sensor inputs (either RTDs or thermocouples) simultaneously.
