Description The Bently Nevada 136711-01 is an Internal Barrier I/O Module specifically designed for the 3500 Machinery Protection System. This module serves as a critical safety component, providing the necessary galvanic isolation and energy limitation required to operate sensors within hazardous (potentially explosive) areas. By integrating these barriers directly into the I/O interface, it eliminates the need for bulky external barrier racks, simplifying system architecture while ensuring compliance with stringent safety standards for hazardous locations.
