New Original Bently Nevada 3500/62-05-00 137110-01 Process Variable Monitor in Stock

The Bently Nevada 137110-01 is a 4-20 mA Barrier I/O Module with Internal Terminations for the 3500/62 Process Variable Monitor in the 3500 Machinery Protection System. It serves as the rear-rack interface between field-mounted 4-20 mA transmitters and the front-facing 3500/62 monitor module. The internal barrier design provides intrinsically safe power to field transmitters in hazardous areas, with built-in zener barriers and fuses, eliminating the need for external safety barriers.

    FAQs

    Q1: What is the primary function of the 137110-01?

    It is the rear I/O module for the 3500/62 Process Variable Monitor, specifically designed for intrinsically safe 4-20 mA current inputs from field transmitters. It provides the physical interface for field wiring and routes conditioned signals to the main monitor card for comparison against alarm setpoints. The internal zener barriers and fuses ensure safe operation in hazardous areas.

    Q2: What is the difference between 137110-01 and 136294-01?

    The 137110-01 is the Barrier I/O Module with intrinsically safe zener barriers and internal terminations, providing I.S. power to field transmitters in hazardous areas. The 136294-01 is the Isolated I/O Module with 500 Vdc isolation but no intrinsic safety barriers. The barrier version is required for Zone 0/1/2 applications.

    Q3: Can the 137110-01 be used with the 3500/62 main board 163179-03?

    Yes. The 137110-01 is designed specifically for the 3500/62 Process Variable Monitor and is compatible with the 163179-03 main board. Both are required together to form a complete process variable monitoring channel.

    Q4: What are the hazardous area approvals for this module?

    When used with the Internal Barrier I/O Module, the 3500/62 system holds ATEX, IECEx, and cNRTLus certifications for hazardous area installation. The internal barriers provide intrinsically safe power to 4-20 mA transducers located in Zone 0/1/2 (gas) or Division 1 (North America) hazardous areas.

    Q5: Is the 137110-01 still available?

    The module is discontinued by the manufacturer but remains a critical part of legacy systems. It is available as New Surplus stock through aftermarket suppliers, with multiple distributors showing inventory availability and 12-month warranties.
