Product Description

Intrinsic Safety and Precision Sensor Interfacing

The 3500/42 (Model: 3500/42) Proximitor Seismic Barrier I/O Module is a critical component for hazardous area monitoring within the Bently Nevada 3500 Series Machinery Protection System. The 135489-01 (Part Number: 135489-01) is specifically engineered with internal zener barriers to provide intrinsically safe connections to transducers located in potentially explosive atmospheres. By limiting the electrical energy delivered to the field sensors, this module ensures that even in the event of a circuit failure, there is insufficient energy to ignite hazardous gases, making it the industry standard for refineries, chemical plants, and upstream oil and gas facilities.
