Product Introduction
The 3500/94M 145988-01 is a Proximitor I/O Module from the Bently Nevada 3500 Series machinery protection system. This module serves as the interface between 3300 XL proximity probes and the 3500 rack, providing signal conditioning, power regulation, and I/O connectivity for critical machinery monitoring applications. The 3500/94M module is designed to support four channels of proximity probe inputs and is fully compatible with the 3500 Series backplane, enabling seamless integration into API 670 compliant protection systems. It is commonly used in applications requiring high reliability, such as turbines, compressors, and large rotating equipment.
