1. Product Introduction: Bently Nevada 3500/62 136483‑01
The 3500/62 (Part Number 136483‑01) is a Discrete Input / Discrete Output (I/O) Module in the 3500 Machinery Protection System. Its principal function is to interface the protection system rack with external digital (binary) signals—accepting discrete inputs (status, logic, fault signals, trip signals) and providing discrete outputs (alarm status, relay commands, interlocks).
By bridging real-world digital signals and the 3500 system’s protection logic, the 3500/62 module enables flexible control, monitoring, and integration of auxiliary systems, shutdown logic, and interlock schemes. It plays a pivotal role in automating protective actions and providing system-level coordination in a machinery protection environment.

3. Applications
The 3500/62 136483‑01 module is applied wherever digital (binary) interactions between protection logic and external systems are needed. Key use cases include:
-
Receiving start/stop commands, system enable/disable status from external control systems
-
Accepting “fault” signals from external sensors or machine controllers
-
Dispatching relay trigger signals, trip outputs, or interlock commands to machinery or protective devices
-
Integrating emergency shutdown logic, permissives, and alarm logic
-
Interfacing with SCADA/DCS systems for status supervision
-
Coordinating multi-module or multi-loop protection strategies
Typical industrial settings include power plants, petrochemical complexes, refineries, heavy manufacturing, and rotating machine control centers.
