Bently Nevada 3500/65 145988-02 16-Channel Temperature Monitor Module for 3500 Rack System

Product Description

3500/65 (PWA part number 145988-02) is a dedicated temperature monitoring card for Bently 3500 series machinery protection rack, manufactured in USABaker Hugh....

It supports 16 mixed temperature signal inputs, compatible with 3/4-wire RTD and isolated tip thermocouples (E/J/K/T type). The module processes field temperature signals, compares readings against user-defined alarm thresholds, and sends data to the rack CPU & System 1 monitoring software.

It supports TMR triple redundant installation for critical turbine safety systems with fault voting logic to avoid single-point failure. Standard single-slot rack plug-in design, widely used as maintenance spare for gas/steam turbines, compressors and power generation equipment.
