Bently Nevada 136711-01 3500 Series I/O Module with Internal Barriers and Internal Terminations

Product Overview

The Bently Nevada 136711-01 functions as a specialized Input/Output module for the 3500 Series Machinery Protection System. This module integrates Internal Intrinsic Safety (IS) Barriers and Internal Terminations, allowing the 3500 rack to interface directly with transducers located in hazardous areas. By consolidating safety barriers and terminal blocks into a single hardware unit, this module eliminates the need for external barrier housings. We supply this component as 100% Brand New original equipment, ensuring factory-certified protection for your critical rotating assets.

Technical Specifications

Engineering Advantages

• Integrated Hazardous Area Protection: The 136711-01 contains built-in zener barriers. These components limit the electrical energy entering hazardous zones, preventing sparks or thermal effects from igniting explosive atmospheres. This integration removes the cost and complexity of mounting separate external safety barriers.

• Space-Efficient Internal Terminations: The internal termination design utilizes high-density screw terminals located directly on the module. This layout saves significant cabinet space, making it ideal for offshore platforms or compact skid-mounted control enclosures where every centimeter of rail space counts.

• Reduced Signal Interference: By terminating field wiring directly at the I/O module, the system minimizes the number of intermediate connection points. Fewer junctions reduce the risk of signal attenuation and shield the sensitive vibration data from electromagnetic interference (EMI).

• Streamlined Installation: Technicians wire the transducers directly to the 136711-01 backplane interface. This direct-to-rack approach simplifies the wiring loop, accelerates commissioning times, and reduces potential points of failure in the signal chain.

FAQs

• Does this module require external safety barriers for Zone 0/1 applications?

  No. The 136711-01 includes internal intrinsic safety barriers designed to limit energy to the transducers. However, you must verify that the specific transducer’s entity parameters match the barrier specifications of this module.

• Can I use the 136711-01 with mass termination cables?

  This specific part number features Internal Terminations, meaning it uses screw terminals for direct field wiring. If your system architecture requires mass termination via multi-pin cables to an external block, you would need the "External Termination" variant of the I/O module.

• How do I ensure the Intrinsic Safety integrity during installation?

  Ensure you maintain proper segregation between the blue "Hazardous Area" wiring and the standard non-IS wiring. Always follow the Bently Nevada 3500 System installation manual regarding ground strapping to ensure the barriers function correctly.

• Is this module a 100% Brand New original product?

  Yes. We supply only 100% Brand New, genuine Bently Nevada parts manufactured in the USA. Each unit arrives in factory-sealed packaging with full serial number traceability for your quality assurance records.
