Bently Nevada 3500/60 133827-01 3500 Series RTD/TC Non-Isolated I/O Module External Terminations

Description

Designed for integration within the 3500 Machinery Protection System, the 3500/60 133827-01 functions as a specialized temperature monitoring input/output interface. This module is configured specifically as an RTD/TC non-isolated I/O module optimized for external termination (ET) architectures. By routing field signals through external termination blocks, it provides a high-density, easily maintainable interface for critical machinery temperature sensor inputs.

The 133827-01 interfaces directly with Resistance Temperature Detectors (RTDs) and Thermocouples (TCs) to monitor temperature profiles on high-value industrial machinery. The physical hardware processes these raw sensor signals and transfers the digitized data to the main 3500/60 Temperature Monitor module, enabling continuous asset protection, alarm state generation, and machinery trip logic integration.

Features

• Accepts direct inputs from standard Thermocouple (TC) and Resistance Temperature Detector (RTD) sensors.
• Non-isolated circuit architecture designed to optimize signal processing path efficiency.
• Supports external termination (ET) blocks to minimize cabinet wiring complexity and streamline field maintenance.
• Fully compatible with standard 3500 series chassis backplanes and monitoring components.
• Hot-swappable hardware design allows module replacement without taking down the entire protection system, subject to site safety procedures.

Applications

• Industrial steam and gas turbine bearing and stator temperature monitoring.
• High-capacity compressor and pump casing diagnostics.
• Large-scale electric motor and generator winding temperature monitoring.
• Critical process piping and heat exchanger temperature protection loops.

Installation Guidelines

• Ensure that the module is installed in the rear I/O slot directly corresponding to the front-facing 3500/60 Temperature Monitor module.
• When routing external termination cables, maintain adequate physical separation from high-voltage power lines to prevent electromagnetic interference.
• Because this module uses a non-isolated architecture, strict adherence to system grounding requirements at the external termination block is critical to avoid ground loop errors.
• Verify that all sensor wiring matches the specific RTD or Thermocouple configuration programmed into the 3500/60 configuration software.
