Description

Product Overview

The 136719-01 (3500/04) is a half-height dedicated IS earthing module for Bently Nevada 3500 machinery protection racks. It provides a low-impedance, isolated intrinsic safety earth reference for all rear barrier I/O cards installed in the chassis. Any rack fitted with internal IS barrier assemblies must deploy this module to satisfy ATEX / IECEx grounding requirements, preventing ground loops and diverting fault energy safely. It does not process vibration or temperature measurement signals; its sole function is hazardous-area safety grounding for proximity, seismic and temperature transducers. It is widely used on turbines, compressors and pumps in refineries, petrochemical and offshore installations.
