Product Description
The Bently Nevada 3500/40 126615-01 Proximitor I/O Module is part of the 3500 Machinery Protection System, specifically designed for use with proximity transducers. It conditions input signals to measure critical parameters such as radial vibration, thrust position, eccentricity, differential expansion, and REBAM. These measurements are continuously compared to user-configured alarm setpoints, ensuring reliable machinery protection and operational insight. The 126615-01 model supports external terminations and works seamlessly with the 3500/40M Proximitor Monitor for accurate and efficient vibration monitoring in industrial environments.
