Bently Nevada 3500/65 172109‑01 16‑Channel Temperature Monitor Module

The Bently Nevada 3500/65 172109‑01 is a hot‑swappable 16‑channel temperature monitoring module for Bently Nevada 3500 machinery protection system. It supports RTD and thermocouple input signals, converts low‑level thermal‑sensor signals into digital process data, and provides configurable alarm thresholds for multi‑point temperature monitoring of large rotating equipment in power‑plant and petrochemical industries.

This rack‑slot I/O module adopts channel‑level isolation design, supports flexible sensor‑type selection via 3500 configuration software, and is equipped with front‑panel LED status indicators for each channel. It works with matched rear termination hardware, and serves as critical aftermarket spare for turbine, compressor and generator protection cabinet maintenance and system retrofitting projects.
