Product Description

High-Density Temperature Monitoring and Protection

The 3500/65 (Model: 3500/65) is a versatile 16-channel temperature monitor designed for the Bently Nevada 3500 Series Machinery Protection System. The 172109-01 (Part Number: 172109-01) I/O module provides the physical interface for both Resistance Temperature Detectors (RTDs) and Isolated Tip Thermocouples (TCs). This module is essential for monitoring bearing temperatures, stator windings, and process fluid temperatures in critical rotating machinery. By providing 16 independent channels in a single slot, it maximizes rack density while maintaining rigorous machinery protection standards, including programmable alarm setpoints and high-speed data integration.

Detailed Technical Specifications

The 3500/65 172109-01 is engineered for precision and industrial-grade reliability, supporting a wide range of sensor types and industrial protocols.

Fault Tolerance and Safety Redundancy

For mission-critical assets, the 3500/65 (172109-01) supports Triple Modular Redundancy (TMR) configurations. In TMR mode, temperature data is cross-checked across three independent paths, ensuring that a single sensor or module failure does not trigger a false trip or leave a machine unprotected. The module also performs continuous self-tests, identifying open or short circuits in the field wiring and immediately notifying operators via the 3500 Configuration Software or System 1. This proactive diagnostic capability is vital for maintaining high availability in power generation and chemical processing facilities.
