The Bently Nevada 136719-01 is an Internal Barrier Earthing I/O Module designed for use within the 3500 Machinery Protection System. This module is an essential component for rack configurations that utilize internal barriers to support intrinsically safe (IS) installations in hazardous areas. It ensures the integrity of the system by providing the required earth connection for internal barrier modules.

Features

  • Half-height module design to optimize rack space.
  • Provides two dedicated I.S. earth connections.
  • Designed specifically for integration with the 3500 series rack system.
  • Supports hazardous area safety compliance by facilitating internal barrier grounding.

Applications

  • Oil & Gas: Essential for monitoring equipment in volatile environments such as compressor stations and pump stations.
  • Power Generation: Used in the protection of turbines, generators, and auxiliary rotating machinery.
  • Petrochemical: Facilitates safe data collection from critical assets situated in hazardous processing zones.

Installation Guidelines

  • The module must be installed in a dedicated monitor position within the 3500 rack.
  • Grouping all internal barrier I/O modules in adjacent rack positions is recommended to simplify wiring and maintenance.
  • When installing standard I/O modules near barrier modules, maintain at least two rack positions of clearance to ensure adequate access for maintenance procedures.
  • Ensure the rack is properly grounded according to the 3500 system documentation before commissioning.
  • Always power down the rack before inserting or removing I/O modules to prevent electrical damage or system faults.

FAQ

What is the primary function of the 136719-01 module?

The 136719-01 serves as an Internal Barrier Earthing I/O Module. Its primary purpose is to provide the necessary intrinsically safe (IS) earth connection for any 3500 rack that contains internal barrier modules.

Does this module affect my rack capacity?

Yes, because the 136719-01 occupies a dedicated monitor slot, it reduces the total available space for other monitor modules in a standard 19-inch 3500 rack to 13 positions.

Is this module compatible with non-3500 systems?

No, this component is specifically engineered for use with the Bently Nevada 3500 Machinery Protection System and is not intended for use in other monitoring platforms.
