Product Introduction

The Bently Nevada 3500/32 125720-02+149986-02 is a 4-Channel Relay Module designed as a critical part of the Bently Nevada 3500 Machinery Protection System. This module is engineered to deliver flexible and reliable relay outputs for system alarm annunciation and shutdown logic. It is widely utilized in turbine supervisory systems, compressor trains, and other critical rotating machinery.

The module is capable of operating four separate relays independently or in voting logic, triggered by conditions detected in other modules within the 3500 system. With its high reliability and robust signal handling, it is an integral part of safety and reliability strategies in demanding industrial environments.
