Description

The Bently Nevada 172115-01 is an External Termination Block (ETB) specifically engineered for integration with the 3500/65 16-Channel Temperature Monitor. In critical machinery protection systems, this ETB serves as the primary physical interface between field-mounted sensors—such as RTDs and isolated tip thermocouples—and the 3500 rack backplane. By relocating the termination point outside of the rack, the 172115-01 facilitates cleaner cable management and simplifies installation in high-density monitoring applications.

Features

• 16-Channel high-density interface for temperature monitoring.
• Designed for RTD and isolated tip thermocouple input signals.
• Provides a secure, organized termination point for field wiring.
• Utilizes Euro-style terminal blocks for reliable signal connection.
• Compatible with 3500/65 Temperature Monitor I/O modules requiring external terminations.

Applications

• Oil & Gas: Centrifugal compressors, pumps, and expanders.
• Power Generation: Steam and gas turbines, generators, and transformers.
• Chemical & Manufacturing: Centrifugal separators, extruders, and heavy-duty reactor pumps.
• Industrial Processing: Monitoring of speed and torque-critical rotating equipment.

Technical Specifications

Installation Guidelines

• Ensure the 3500 rack is powered down before installing or removing any I/O modules or associated termination blocks.
• Land field-mounted RTD or isolated tip thermocouple wires directly into the Euro-style connectors on the 172115-01 block.
• For 3-wire RTDs, connect wires to the designated terminals (A, B, and common).
• Note that 4-wire RTD configurations may require specific I/O module modifications (refer to 179952-01 documentation).
• Maintain proper shielding practices for all field wiring to minimize EMI/RFI interference in the monitoring loop.
• Ensure the block is mounted in a location that allows for adequate ventilation and access for maintenance.

FAQ
