The Bently Nevada 114M5335-01 is a Low Voltage DC Power Input Module (PIM) designed for the 3500/15 Power Supply system within the Bently Nevada 3500 Series Machinery Protection System. This module serves as the physical interface between an external 20 to 30 Vdc power source and the 3500 rack's power supply module.

Features

• Low-Voltage DC input range (20 to 30 Vdc).
• Designed for integration with the 3500/15 Power Supply system.
• Supports power redundancy when configured with dual modules.
• Includes internal fuse protection against over-voltage conditions.
• High electromagnetic compatibility (EMC) for industrial environments.

Applications

This module is used in critical machinery protection systems, including:

• Turbines: Steam, hydraulic, industrial gas, and aeroderivative gas turbines.
• Compressors: Centrifugal, axial, reciprocating, and screw compressors.
• Pumps: Horizontal and vertical centrifugal pumps, and reciprocating pumps.
• Generators and electric motors.
• Auxiliary equipment such as fans, blowers, agitators, and turbo-expanders.

Technical Specifications

Installation Guidelines

• The 114M5335-01 must be installed in the designated slots on the left side of the 3500 rack, positioned directly behind the associated 114M5330-01 Low Voltage DC Power Supply.
• Ensure the system is powered down before inserting or removing the module to prevent electrical damage.
• Use the integrated screw terminals for secure connection of the DC power source.
• Maintain proper ventilation within the cabinet to ensure the module operates within its specified temperature range.
• For redundant configurations, ensure both PIMs are correctly seated to allow for seamless load sharing and hot-swapping capabilities.

FAQ

What is the function of the 114M5335-01?

It acts as the power input terminal for the 3500 rack, receiving 20 to 30 Vdc and distributing it to the power supply module.

Does the 114M5335-01 support hot-swapping?

Yes, when the 3500 rack is configured with redundant power supplies, the system can maintain operation if one module is removed or fails.

What is the difference between 114M5330-01 and 114M5335-01?

The 114M5330-01 is the Low Voltage DC Power Supply module that converts input power, while the 114M5335-01 is the Power Input Module (PIM) that provides the physical interface and terminal connection for the DC source.
